I’m going to show you how to install Backtrack 3 to an USB Flash Drive with persistent changes. For people that don’t know what Backtrack is, please look at their respective website.
Note: In this small tutorial I assume you understand the concepts of partitioning and have some experience with Linux as well.
Oke, let’s begin!
- USB Flash Drive of 1GB or more…
- BackTrack 3 USB Version (Extended) iso image (bt3final_usb.iso).
- Partitioning application like: Paragon Partition Manager or similar.
- Partition your USB Flash Drive as follows:
• One partition for BT3; should be of 1GB or more (900MB minimum!). Format it with FAT32 & Label it as “BT3”.
• 2nd partition for changes; should be of 100MB or more. Format it with Ext3 & Label it as “CHANGES”.
• 3rd partition (optional); Used for swap. Format it as Linux Swap.
- Using WinRAR; unrar the iso image. Or mount it with your preferred application.
- Copy both folders (“boot” & “BT3”) to the USB Flash Drive’s BT3 partition.
- Execute bootinst.sh/bootinst.bat according the OS you’re currently running. Both files are located in the “boot” folder of your USB Flash Drive.
• Under Linux:
• Under Windows (as Admin):
double click bootinst.bat
- Boot your USB Flash Drive and select “BT3 Graphics mode (KDE)” or whatever you prefer that doesn’t are: “BT3 Graphics mode with Persistent Changes”.
• Go to your CHANGES partition. (Ex. /mnt/sdb2)
• Create a folder named “changes”
• Now go to your BT3 partition. (Ex. /mnt/sdb1)
• Edit your syslinux.cfg that should be located in the “boot” folder of your USB Flash Drive.
• Locate this line: “MENU LABEL BT3 Graphics mode with Persistent Changes”•
• Replace: “changes=/changes/slaxsave.dat” with “changes=/dev/sdb2” (Change sdb2 according to your system)
• Save the file!
• Note: You’re free to re-arrange your boot menu and change the default TIMEOUT.
- Reboot and Boot your BT3 USB in “BT3 Graphics mode with Persistent Changes”.
