DUAL
BOOTING WINDOWS XP AND BT2
This method of dual booting will
not require you to format the windows
part of your hard drive and should not corrupt your current
installation in anway. It also presumes that you have one partiton with
Windows installed.
Insert the backtrack CD, boot
up, log on as normal and 'startx'
Once you are at the desktop open
up a terminal window and 'word for
word' complete the following (it should take around 30 minutes to
complete)
**This will repartition the
empty space on your hard drive, so backup your Windows data if you are
worried about losing it**
Anything in between the '&'
signs are explanations of what you
are doing and obviously should not be entered into the command.
If you have SATA hard drives
then you will have ‘sda’ in place of ‘hda’ so edit the commands
accordingly.
| Code: |
bt ~ #mount &This will show you all the partitions BT can see& tmpfs on / type tmpfs (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) usbfs on /proc/bus/usb type usbfs (rw,devgid=10,devmode=0666) /dev/hda1 on /mnt/hda1 type ntfs (ro,noatime) bt ~ # umount /mnt/hda1/ &We can't make changes to a hard drive that is mounted, so we need to un-mount it first& bt ~ # qtparted &start qtparted which we will use to resize the existing partition& |
At this
point a graphical interface will open to allow you to resize your
primary partion (typically your 'C drive')
Highlight /dev/hda on the left -
then on the right you will see a
rectangle which represents your hard drive. Right click it and select
resize, on the new window that opens up drag and drop the right of the
green triangle to set the size of the partition you want to give to
Windows. I halved it for my system as my Windows install isn’t used for
my everyday stuff, so does not need a large amount of space but you can
set it to whatever you desire, I would say give at least 8GB to
backtrack.
Click OK and then click on the
disc icon in the top left (next to
the green arrow) this will commit the changes to the disc. You do not
have to reboot at this point but I have long ago got into the habit of
doing so after making any changes to the hard drive structure.
After you have applied the
changes, exit from qtparted and drop back into your terminal window..
You may see something similar to
the following, which qtparted logged to your terminal whilst you
weren’t looking.

Just ignore it and carry on.

Have fun. ReiserFS is successfully created on /dev/hda4. |
Reboot now, when you have started up
again open a new terminal window
and carry on from here. Pay particular attention to the '/', they have
to be entered exactly as shown
| Code: |
bt #v# mkdir /mnt/backtrack &create the specified directory& bt ~ # mount /dev/hda4 /mnt/backtrack/ &sets the mount point for hda4 to the directory we have just created& bt ~ # mkdir /mnt/backtrack/boot/ &again create the specified directory& bt ~ # mount /dev/hda2 /mnt/backtrack/boot/ &set the mount point to be the directory we have just created& bt ~ # cp --preserve -R /{bin,dev,home,pentest,root,usr,etc,lib,opt,sbin,var} /mnt/backtrack &copies the files recursively to the specified directory - this is in essence installing backtrack to the directory we have specified.

Now we need to edit the lilo script
to allow us to dual boot the system, this will sit on the first part of
the hard drive.
When you boot up this config
file is the first thing read and
determines which partition will get control of your system, the one
with Windows installed, or the one with Backtrack installed
| Code: |
bt / # nano /etc/lilo.conf |
Edit the file to represent the
following:
| Code: |
# LILO configuration file # generated by 'liloconfig' # # Start LILO global section lba32 # Allow booting past 1024th cylinder with a recent BIOS boot = /dev/hda #message = /boot/boot_message.txt prompt timeout = 1200 # Override dangerous defaults that rewrite the partition table: change-rules reset # VESA framebuffer console @ 1024x768x256 vga = 773 # Normal VGA console # vga = normal # VESA framebuffer console @ 1024x768x64k # vga=791 # VESA framebuffer console @ 1024x768x32k # vga=790 # VESA framebuffer console @ 1024x768x256 # vga=773 # VESA framebuffer console @ 800x600x64k # vga=788 # VESA framebuffer console @ 800x600x32k # vga=787 # VESA framebuffer console @ 800x600x256 # vga=771 # VESA framebuffer console @ 640x480x64k # vga=785 # VESA framebuffer console @ 640x480x32k # vga=784 # VESA framebuffer console @ 640x480x256 # vga=769 # End LILO global section # Linux boot partition image = /boot/vmlinuz root = /dev/hda4 label = BackTrack2 &you can call this what ever you want& read-only # End Linux Boot partition # Windows bootable partition config begins other = /dev/hda1 label = Windows XP &You can call this what ever you want& table = /dev/hda # Windows bootable partition config ends |
Anything with a # can be removed for
brevity reasons if you so wish, I
have kept them in to more truly represent the file you will see
Save the file by hitting CTL +
X, press Y to save the changes
| Code: |
bt / # lilo -v &verbosely write the file to the Master Boot Record - this will overwrite the current Windows MBR and will give you the option to chose your operating system next time you reboot& LILO version 22.7.1, Copyright (C) 1992-1998 Werner Almesberger Development beyond version 21 Copyright (C) 1999-2005 John Coffman Released 17-Sep-2005 and compiled at 00:33:53 on Aug 8 2006. Reading boot sector from /dev/hda Using MENU secondary loader Calling map_insert_data Boot image: /boot/vmlinuz Added backtrack2 * Boot other: /dev/hda1, on /dev/hda, loader CHAIN Added Windows Writing boot sector. Backup copy of boot sector in /boot/boot.0300 |
Ensure there are no fatal errors here
at all - if there are, resolve
them BEFORE rebooting. If you do get an error then 9 times out of 10
you will not have edited the lilo.conf file correctly
| Code: |
bt / #exit bt ~ #reboot |
When your system now starts up you will be presented
with the red lilo
screen displaying Windows and BackTrack2 (or whatever you put in the
'label =' part of the lilo.conf) obviously select Windows to boot into
your Windows OS, or select BackTrack2 to boot into backtrack.
Enjoy :-)
