How To Install Backtrack4 Using Grub On Ubuntu


Backtrack is an operating system that is specially designed for networking security. Bactrack OS is based on Linux. As of this writing the latest version of Bactrack is Backtrack4 with many, many useful applications. Before installing BT4, make sure you have installed Ubuntu on your computer so we can use Ubuntu's Grub for booting.

Follow these steps to install and configure dual booting Ubuntu / Backtrack4.
  1. Prepare your PC
    Ubuntu OS installed on sda2
    BT4 will install on sda3
  2. Run BT4 using LiveCD
    user : root
    password : toor
    #startx
  3. Installation process

    # mkfs.ext3 /dev/sda3

    # mkdir /mnt/BT4
    # mkdir /mnt/ubuntu
    # mount /dev/sda3 /mnt/BT4
    # mount /dev/sda2 /mnt/ubuntu
    # mkdir /mnt/BT4/boot

    # cp /boot/vmlinuz /mnt/BT4/boot
    # cp --preserve -R /{bin,dev,home,pentest,root,usr,etc,lib,opt,sbin,var} /mnt/BT4/
    # mkdir /mnt/BT4/{mnt,proc,sys,tmp}
    # mount --bind /dev/ /mnt/BT4/dev/
    # mount -t proc proc /mnt/BT4/proc/
  4. Edit Grub of Ubuntu
    # vi /mnt/ubuntu/boot/grub/menu.lst

    #you must insert this at bottom page:
    title Backtrack4
    rootnoverify (hd0,2)
    kernel /boot/vmlinuz vga=791 root=/dev/sda3 ro autoexec=xconf;kdm
    boot

  5. Exit and restart your PC. Select “Backtrack4” and login.
  6. Registering sda3 to fstab
    We must register /dev/sda2 and /dev/sda3 so either Ubuntu or BT4 can be booted.

    # mkdir /mnt/BT4
    # mkdir /mnt/ubuntu
    # vi /etc/fstab

    /dev/sda2 /mnt/ubuntu ext3
    /dev/sda3 /mnt/BT4 ext3
