Here's a road map for the steps you will take during the installation process.
Before you start, make sure to back up every file that is now on your system. If this is the first time a non-native operating system has been installed on your computer, it's quite likely you will need to re-partition your disk to make room for Debian GNU/Linux. Anytime you partition your disk, you should count on losing everything on the disk, no matter what program you use to do it. The programs used in installation are quite reliable and most have seen years of use; but they are also quite powerful and a false move can cost you. Even after backing up be careful and think about your answers and actions. Two minutes of thinking can save hours of unnecessary work.
If you are creating a multi-boot system, make sure that you have the distribution media of any other present operating systems on hand. Especially if you repartition your boot drive, you might find that you have to reinstall your operating system's boot loader, or in many cases the whole operating system itself and all files on the affected partitions.

Many brand name products work without trouble on Linux. Moreover, hardware for Linux is improving daily. However, Linux still does not run as many different types of hardware as some operating systems.
In particular, Linux usually cannot run hardware that requires a running version of Windows to work.
Although some Windows-specific hardware can be made to run on Linux, doing so usually requires extra effort. In addition, Linux drivers for Windows-specific hardware are usually specific to one Linux kernel. Therefore, they can quickly become obsolete.
So called win-modems are the most common type of this hardware. However, printers and other equipment may also be Windows-specific.
You can check hardware compatibility by:
If your computer is connected to a network 24 hours a day (i.e., an Ethernet or equivalent connection — not a PPP connection), you should ask your network's system administrator for this information. On the other hand, if your administrator tells you that a DHCP server is available and is recommended, then you don't need this information because the DHCP server will provide it directly to your computer during the installation process.
If your computer's only network connection is via a serial line, using PPP or an equivalent dialup connection, you will not be able to install the base system over the network. To install the system in this case, you must use a CD, pre-load the base packages on an existing hard disk partition, or prepare floppy disks containing the base packages. See Setting Up PPP, Section 8.9 below for information on setting up PPP under Debian once the system is installed.
It is important to decide what type of machine you are creating. This will determine the disk space requirements for your Debian system.
Once you have gathered information about your computer's hardware, check that your hardware will let you do the type of installation that you want to do.
Depending on your needs, you might manage with less than some of the recommended hardware listed in the table below. However, most users risk being frustrated if they ignore these suggestions. A Pentium 100 is the minimum recommended for desktop systems, and a Pentium II-300 for a Server.
Recommended Minimum System Requirements +------------------------------------------+ |Install Type| RAM | Hard Drive | |------------+--------------+--------------| |No desktop | 16 megabytes | 450 megabytes| |------------+--------------+--------------| |With Desktop| 64 megabytes | 1 gigabyte | |------------+--------------+--------------| |Server | 128 megabytes| 4 gigabytes | +------------------------------------------+
Here is a sampling of some common Debian system configurations. You can also get an idea of the disk space used by related groups of programs by referring to Disk Space Needed for Tasks, Section 11.4.
Remember that these sizes don't include all the other materials which are
usually to be found, such as user files, mail, and data. It is always best to
be generous when considering the space for your own files and data. Notably,
/var partition contains a lot of state information.
dpkg files (with information on all installed packages) can
easily consume 20MB; with logs and the rest, you should usually allocate at
least 50MB for
Partitioning your disk simply refers to the act of breaking up your disk into sections. Each section is then independent of the others. It's roughly equivalent to putting up walls in a house; if you add furniture to one room it doesn't affect any other room.
If you already have an operating system on your system (Windows95, Windows NT, OS/2, MacOS, Solaris, FreeBSD, …) and want to stick Linux on the same disk, you will need to repartition the disk. Debian requires its own hard disk partitions. It cannot be installed on Windows or MacOS partitions. It may be able to share some partitions with other Linux systems, but that's not covered here. At the very least you will need a dedicated partition for the Debian root.
You can find information about your current partition setup by using a partitioning tool for your current operating system , such as fdisk or PartitionMagic . Partitioning tools always provide a way to show existing partitions without making changes.
In general, changing a partition with a file system already on it will destroy any information there. Thus you should always make backups before doing any repartitioning. Using the analogy of the house, you would probably want to move all the furniture out of the way before moving a wall or you risk destroying it. Luckily, there is an alternative for some users; see Lossless Repartitioning When Starting From DOS, Win-32 or OS/2, Section 220.127.116.11.
If your computer has more than one hard disk, you may want to dedicate one of the hard disks completely to Debian. If so, you don't need to partition that disk before booting the installation system; the installer's included partitioning program can handle the job nicely.
If your machine has only one hard disk, and you would like to completely replace the current operating system with Debian GNU/Linux, you also can wait to partition as part of the installation process (Partitioning for Debian, Chapter 6), after you have booted the installation system. However this only works if you plan to boot the installer system from floppies, CD-ROM or files on a connected machine. Consider: if you boot from files placed on the hard disk, and then partition that same hard disk within the installation system, thus erasing the boot files, you'd better hope the installation is successful the first time around. At the least in this case, you should have some alternate means of reviving your machine like the original system's installation floppies or CDs.
If your machine already has multiple partitions, and enough space can be provided by deleting and replacing one or more of them, then you too can wait and use the Debian installer's partitioning program. You should still read through the material below, because there may be special circumstances like the order of the existing partitions within the partition map, that force you to partition before installing anyway.
In all other cases, you'll need to partition your hard disk before starting the installation to create partition-able space for Debian. If some of the partitions will be owned by other operating systems, you should create those partitions using native operating system partitioning programs. We recommend that you do not attempt to create Debian Linux partitions using another operating system's tools. Instead, you should just create the native operating system's partitions you will want to retain.
If you are going to install more than one operating system on the same machine, you should install all other system(s) before proceeding with Linux installation. Windows and other OS installations may destroy your ability to start Linux, or encourage you to reformat non-native partitions.
You can recover from these actions or avoid them, but installing the native system first saves you trouble.
If you currently have one hard disk with one partition (a common setup for desktop computers), and you want to multi-boot the native operating system and Debian, you will need to:
If you are manipulating existing FAT or NTFS partitions, it is recommended that you either use the scheme below or native Windows or DOS tools. Otherwise, it is not really necessary to partition from DOS or Windows; the Linux partitioning tools will generally do a better job.
But if you have a large IDE disk, and are using neither LBA addressing, overlay drivers (sometimes provided by hard disk manufacturers), nor a new (post 1998) BIOS that supports large disk access extensions, then you must locate your Debian boot partition carefully. In this case, you will have to put the boot partition into the first 1024 cylinders of your hard drive (usually around 524 megabytes, without BIOS translation). This may require that you move an existing FAT or NTFS partition.
One of the most common installations is onto a system that already contains DOS (including Windows 3.1), Win32 (such as Windows 95, 98, NT), or OS/2, and it is desired to put Debian onto the same disk without destroying the previous system. As explained in the Deciding on Debian Partitions and Sizes, Section 6.1, decreasing the size of an existing partition will almost certainly damage the data on that partition unless certain precautions are taken. The method described here, while not guaranteed to protect your data, works extremely well in practice. As a precaution, you should make a backup.
Before going any further, you should have decided how you will be dividing up the disk. The method in this section will only split a partition into two pieces. One will contain the original OS and the other will be used for Debian. During the installation of Debian, you will be given the opportunity to use the Debian portion of the disk as you see fit, i.e., as swap or as a file system.
The idea is to move all the data on the partition to the beginning, before changing the partition information, so that nothing will be lost. It is important that you do as little as possible between the data movement and repartitioning to minimize the chance of a file being written near the end of the partition as this will decrease the amount of space you can take from the partition.
The first thing needed is a copy of
fips which is available in the
tools/ directory on your nearest Debian mirror. Unzip the archive
and copy the files
ERRORS.TXT to a bootable floppy. A bootable floppy can be created
using the command
sys a: under DOS.
fips comes with
very good documentation which you may want to read. You will definitely need
to read the documentation if you use a disk compression driver or a disk
manager. Create the disk and read the documentation before you
defragment the disk.
The next thing needed is to move all the data to the beginning of the
defrag, which comes standard with DOS 6.0 and later
can easily do the job. See the
fips documentation for a list of
other software that may do the trick. Note that if you have Windows 95, you
defrag from there, since DOS doesn't understand VFAT,
which is used to support for long filenames, used in Windows 95 and higher.
After running the defragmenter (which can take a while on a large disk), reboot
fips disk you created in the floppy drive. Simply type
a:\fips and follow the directions.
Note that there are many other other partition managers out there, in case
fips doesn't do the trick for you.
If you are partitioning for DOS drives, or changing the size of DOS partitions,
using Linux tools, many people experience problems working with the resulting
FAT partitions. For instance, some have reported slow performance, consistent
scandisk, or other weird errors in DOS or Windows.
Apparently, whenever you create or resize a partition for DOS use, it's a good
idea to fill the first few sectors with zeros. Do this prior to running DOS's
format command, from Linux:
dd if=/dev/zero of=/dev/hdXX bs=512 count=4
This section explains how to install Debian GNU/Linux from an existing Unix or Linux system, without using the ncurses-based, menu-driven installer as explained in the rest of the manual. This "cross-install" HOWTO has been requested by users switching to Debian GNU/Linux from Redhat, Mandrake, and SUSE. In this section some familiarity with entering *nix commands and navigating the file system is assumed. In this section, $ symbolizes a command to be entered in the user's current system, while # refers to a command entered in the Debian chroot.
Once you've got the new Debian system configured to your preference, you can migrate your existing user data (if any) to it, and keep on rolling. This is therefore a "zero downtime" Debian GNU/Linux install. It's also a clever way for dealing with hardware that otherwise doesn't play friendly with various boot or installation media.
With your current *nix partitioning tools, repartition the hard drive as needed, creating at least one filesystem plus swap. You need at least 150MB of space available for a console only install, or at least 300MB if you plan to install X.
To create file systems on your partitions. For example, to create an ext3 file
system on partition
/dev/hda6 (that's our example root partition):
$ mke2fs -j /dev/hda6
To create an ext2 file system instead, omit -j.
Initialize and activate swap (substitute the partition number for your intended Debian swap partition):
$ mkswap /dev/hda5 $ sync; sync; sync $ swapon /dev/hda5
Mount one partition as
/mnt/debinst (the installation point, to be
the root (
/) filesystem on your new system). The mount point name
is strictly arbitrary, it is referenced later below.
$ mkdir /mnt/debinst $ mount /dev/hda6 /mnt/debinst
The tool that the Debian installer uses, which is recognized as the official
way to install a Debian base system, is
debootstrap. It uses
wget, but otherwise depends only on
wget if it isn't already on your current system, then download and
If you have an rpm-based system, you can use alien to convert the .deb into
.rpm, or download an rpm-ized version at
Or, you can use the following procedure to install it manually. Make a work folder for extracting the .deb into:
$ mkdir work $ cd work
debootstrap binary is located in the Debian archive (be sure
to select the proper file for your architecture). Download the
debootstrap .deb from the
copy the package to the work folder, and extract the binary files from it. You
will need to have root privileges to install the binaries.
$ ar -xf debootstrap_0.X.X_arch.deb $ cd / $ zcat < /full-path-to-work/work/data.tar.gz | tar xv
The current version of
debootstrap, at least for i386, has been
compiled with glibc 2.3. Therefore if you are upgrading from Redhat 6.0, you
will need to obtain the source files and re-compile.
debootstrap can download the needed files directly from the
archive when you run it. You can substitute any Debian archive mirror for
http.us.debian.org/debian in the command example below, preferably
a mirror close to you network-wise. Mirrors are listed at
debootstrap, the PATH needs to include
/sbin for subsidiary program calls.
If you have a woody version Debian GNU/Linux CD mounted at /cdrom, you could substitute a file URL instead of the http URL: file:/cdrom/debian/
Substitute one of the following for ARCH in the
debootstrap command: alpha, arm,
hppa, i386, ia64, m68k,
mips, mipsel, powerpc,
s390, or sparc.
$ /usr/sbin/debootstrap --arch ARCH woody \ /mnt/debinst http://http.us.debian.org/debian
debootstrap can use the
basedebs.tar file, if you
have already downloaded it ahead of time. The
is generated only every once in a while, so you'll get the latest version of
the base system by pointing
debootstrap directly to a Debian
archive as shown in the previous section.
basedebs.tar file is found in the
base-images-current directory of the Debian archive for your
architecture, for example:
Substitute one of the following for ARCH in the
debootstrap command: alpha, arm,
hppa, i386, ia64, m68k,
mips, mipsel, powerpc,
s390, or sparc.
$ /usr/sbin/debootstrap --arch ARCH --unpack-tarball \ /path-to-downloaded/basedebs.tar woody /mnt/debinst
Now you've got a real Debian system, though rather lean, on disk.
Chroot into it:
$ chroot /mnt/debinst /bin/bash
You need to create
# editor /etc/fstab
Here is a sample you can modify to suit:
# /etc/fstab: static file system information. # # file system mount point type options dump pass /dev/XXX / ext2 defaults 0 0 /dev/XXX /boot ext2 ro,nosuid,nodev 0 2 /dev/XXX none swap sw 0 0 proc /proc proc defaults 0 0 /dev/fd0 /mnt/floppy auto noauto,rw,sync,user,exec 0 0 /dev/cdrom /mnt/cdrom iso9660 noauto,ro,user,exec 0 0 /dev/XXX /tmp ext2 rw,nosuid,nodev 0 2 /dev/XXX /var ext2 rw,nosuid,nodev 0 2 /dev/XXX /usr ext2 rw,nodev 0 2 /dev/XXX /home ext2 rw,nosuid,nodev 0 2
Use mount -a to mount all the file systems you have specified in
/etc/fstab, or to mount file systems individually use:
# mount /path # e.g.: mount /usr
You can mount the proc file system multiple times and to arbitrary locations, though /proc is customary. If you didn't use mount -a, be sure to mount proc before continuing:
# mount -t proc proc /proc
A RedHat user reports that for his system, this should instead be
# mount -t proc none /proc
To configure your keyboard:
# dpkg-reconfigure console-data
To configure networking, edit
# editor /etc/network/interfaces
Here are some simple examples from
###################################################################### # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # See the interfaces(5) manpage for information on what options are # available. ###################################################################### # We always want the loopback interface. # auto lo iface lo inet loopback # To use dhcp: # # auto eth0 # iface eth0 inet dhcp # An example static IP setup: (broadcast and gateway are optional) # # auto eth0 # iface eth0 inet static # address 192.168.0.42 # network 192.168.0.0 # netmask 255.255.255.0 # broadcast 192.168.0.255 # gateway 192.168.0.1
Enter your nameserver(s) and search directives in
# editor /etc/resolv.conf
# search hqdom.local\000 # nameserver 10.1.1.36 # nameserver 192.168.9.100
Enter your system's host name (2 to 63 characters):
# echo DebianHostName > /etc/hostname
If you have multiple network cards, you should arrange the names of driver
modules in the
/etc/modules file into the desired order. Then
during boot, each card will be associated with the interface name (eth0, eth1,
etc.) that you expect.
Set your timezone, add a normal user, and choose your
To configure your locale settings to use a language other than English, install the locales support package and configure it:
# apt-get install locales # dpkg-reconfigure locales
NOTE: Apt must be configured before, ie. during the base-config phase. Before using locales with character sets other than ASCII or latin1, please consult the appropriate localisation HOWTO.
If you intend to boot this system, you probably want a Linux kernel and a boot loader. Identify available pre-packaged kernels with
# apt-cache search kernel-image
Then install your choice using its package name.
# apt-get install kernel-image-2.X.X-arch-etc
To make your Debian GNU/Linux system bootable, set up your boot loader to load the installed kernel with your new root partition.
Check man lilo.conf for instructions on setting up the bootloader. If you are keeping the system you used to install Debian, just add an entry for the Debian install to your existing lilo.conf. You could also copy it to the new system and edit it there. After you are done editing, call lilo (remember it will use lilo.conf relative to the system you call it from).
Here is a basic /etc/lilo.conf as an example:
boot=/dev/hda6 root=/dev/hda6 install=/boot/boot-menu.b delay=20 lba32 image=/vmlinuz label=Debian
This section will walk you through pre-installation hardware setup, if any, that you will need to do prior to installing Debian. Generally, this involves checking and possibly changing firmware settings for your system. The ``firmware'' is the core software used by the hardware; it is most critically invoked during the bootstrap process (after power-up). Known hardware issues affecting the reliability of Debian GNU/Linux on your system are also highlighted.
BIOS provides the basic functions needed to boot your machine to allow your operating system to access your hardware. Your system probably provides a BIOS set-up menu, which is used to configure the BIOS. Before installing, you must ensure that your BIOS is setup correctly; not doing so can lead to intermittent crashes or an inability to install Debian.
The rest of this section is lifted from the
FAQ, answering the question, "How do I enter the CMOS
configuration menu?". How you access the BIOS (or ``CMOS'') configuration
menu depends on who wrote your BIOS software:
[From: email@example.com (Shaun Burnet)]
Information on invoking other BIOS routines can be found in
Some Intel x86 machines don't have a CMOS configuration menu in the BIOS. They
require a software CMOS setup program. If you don't have the Installation
and/or Diagnostics diskette for your machine, you can try using a
shareware/freeware program. Try looking in
Many BIOS set-up menus allow you to select the devices that will be used to
bootstrap the system. Set this to look for a bootable operating system on
A: (the first floppy disk), then optionally the first CD-ROM
device (possibly appearing as
E:), and then
C: (the first hard disk). This setting enables you to boot
from either a floppy disk or a CD-ROM, which are the two most common boot
devices used to install Debian.
If you have a newer SCSI controller and you have a CD-ROM device attached to it, you are usually able to boot from the CD-ROM. All you have to do is enable booting from a CD-ROM in the SCSI-BIOS of your controller.
Here are some details about how to set the boot order. Remember to reset the boot order after Linux is installed, so that you restart your machine from the hard drive.
Common entries on IDE machines are C, A, cdrom or A, C, cdrom .
C is the hard drive, and A is the floppy drive.
You can start the SCSI setup utility after the memory check and the message about how to start the BIOS utility displays when you start your computer.
The keystrokes you need depend on the utility. Often, it is Ctrl-F2. However, consult your hardware documentation for the exact keystrokes.
Some BIOS systems (such as Award BIOS) allow you to automatically set the CD speed. You should avoid that, and instead set it to, say, the lowest speed. If you get seek failed error messages, this may be your problem.
If your system provides both extended and expanded memory, set it so that there is as much extended and as little expanded memory as possible. Linux requires extended memory and cannot use expanded memory.
Disable any virus-warning features your BIOS may provide. If you have a virus-protection board or other special hardware, make sure it is disabled or physically removed while running GNU/Linux. These aren't compatible with GNU/Linux; moreover, due to the file system permissions and protected memory of the Linux kernel, viruses are almost unheard of.
Your motherboard may provide shadow RAM or BIOS caching. You may see settings for ``Video BIOS Shadow'', ``C800-CBFF Shadow'', etc. Disable all shadow RAM. Shadow RAM is used to accelerate access to the ROMs on your motherboard and on some of the controller cards. Linux does not use these ROMs once it has booted because it provides its own faster 32-bit software in place of the 16-bit programs in the ROMs. Disabling the shadow RAM may make some of it available for programs to use as normal memory. Leaving the shadow RAM enabled may interfere with Linux access to hardware devices.
If your BIOS offers something like ``15-16 MB Memory Hole'', please disable that. Linux expects to find memory there if you have that much RAM.
We have a report of an Intel Endeavor motherboard on which there is an option called ``LFB'' or ``Linear Frame Buffer''. This had two settings: ``Disabled'' and ``1 Megabyte''. Set it to ``1 Megabyte''. When disabled, the installation floppy was not read correctly, and the system eventually crashed. At this writing we don't understand what's going on with this particular device — it just worked with that setting and not without it.
If your motherboard provides Advanced Power Management (APM), configure it so that power management is controlled by APM. Disable the doze, standby, suspend, nap, and sleep modes, and disable the hard disk's power-down timer. Linux can take over control of these modes, and can do a better job of power-management than the BIOS. The version of the operating system kernel on the installation floppies does not, however, use APM, because we've had reports of one laptop system crashing when the Linux APM driver is configured. Once you've installed Linux, you can build a custom-configured version of the Linux kernel; see Compiling a New Kernel, Section 9.6 for instructions.
Many people have tried operating their 90 MHz CPU at 100 MHz, etc. It
sometimes works, but is sensitive to temperature and other factors and can
actually damage your system. One of the authors of this document over-clocked
his own system for a year, and then the system started aborting the
gcc program with an unexpected signal while it was compiling the
operating system kernel. Turning the CPU speed back down to its rated value
solved the problem.
gcc compiler is often the first thing to die from bad memory
modules (or other hardware problems that change data unpredictably) because it
builds huge data structures that it traverses repeatedly. An error in these
data structures will cause it to execute an illegal instruction or access a
non-existent address. The symptom of this will be
gcc dying from
an unexpected signal.
The very best motherboards support parity RAM and will actually tell you if your system has a single-bit error in RAM. Unfortunately, they don't have a way to fix the error, thus they generally crash immediately after they tell you about the bad RAM. Still, it's better to be told you have bad memory than to have it silently insert errors in your data. Thus, the best systems have motherboards that support parity and true-parity memory modules; see Fake or ``Virtual'' Parity RAM, Section 2.6.3.
If you do have true-parity RAM and your motherboard can handle it, be sure to enable any BIOS settings that cause the motherboard to interrupt on memory parity errors.
Many systems have a turbo switch that controls the speed of the CPU. Select the high-speed setting. If your BIOS allows you to disable software control of the turbo switch (or software control of CPU speed), do so and lock the system in high-speed mode. We have one report that on a particular system, while Linux is auto-probing (looking for hardware devices) it can accidentally touch the software control for the turbo switch.
Many users of Cyrix CPUs have had to disable the cache in their systems during installation, because the floppy disk has errors if they do not. If you have to do this, be sure to re-enable your cache when you are finished with installation, as the system runs much slower with the cache disabled.
We don't think this is necessarily the fault of the Cyrix CPU. It may be something that Linux can work around. We'll continue to look into the problem. For the technically curious, we suspect a problem with the cache being invalid after a switch from 16-bit to 32-bit code.
You may have to change some settings or jumpers on your computer's peripheral cards. Some cards have setup menus, while others rely on jumpers. This document cannot hope to provide complete information on every hardware device; what it hopes to provide is useful tips.
If any cards provide ``mapped memory'', the memory should be mapped somewhere between 0xA0000 and 0xFFFFF (from 640K to just below 1 megabyte) or at an address at least 1 megabyte greater than the total amount of RAM in your system.
If you have no AT-style keyboard and only a USB model, you will need to enable legacy AT keyboard emulation in your BIOS setup. Consult your main board manual and look in the BIOS for "Legacy keyboard emulation" or "USB keyboard support" options. It must be enabled in order to boot the installation system. If you enabled this option and it is working for you, you are fine and can go ahead.
If you cannot find this option, it might be that it is always enabled and you can continue. It also might mean that the BIOS does not provide any emulation support (bad luck here).
If you find the option and enable it, but the emulation stops working soon after the kernel started, then you have bad luck too. You could try the "bf2.4" flavor where the root floppy brings USB modules. If you are installing with floppy disks, you would need the keyboard once before the USB modules can be loaded. Specifying the "keytimer" option at boot prompt may help in this case.
Sometimes, the emulation hangs but it wakes up after few minutes, so you could wait some time and try to continue. To fix this behavior, you could load Linux' own drivers for USB keyboards. For this, use "modconf" (Step "Configure Device Driver Modules") and load usb-uhci or usb-ohci modules.
The Linux Kernel can not always detect what amount of RAM you have. If this is the case please look at Boot Parameter Arguments, Section 5.1.
