Yup. You guessed it. A new how-to that walks you through creating a bootable Backtrack 4 USB thumbdrive. This time we don't need to worry about updating Firefox or nmap though. You can find it at the link below.

Backtrack 4 - USB/Persistent Changes/Nessus

As always, let me know if you find any problems or have any suggestions.

Great tutorial. One question: the ‘changes’ folder is added to the “APPEND …” line, and assigned a device, e.g., changes=/dev/sdb2.” BUT, doesn’t this mean that a different drive letter assignment, due perhaps to another usb drive being connected during a subsequent boot, means that “/dev/sdb2” is no longer valid? The BT drive might then be, “/dev/sdc2,” or whatever, right?

I ask this as a successful session ended and then I rebooted in a different drive setup and the persistent login option rendered only partial desktop functionality.

I would love to have a truly portable BT usb!
Thanks again,

Thanks Mike.

I have had the exact same problem you mention before, although never on the same machine. I usually just edit the syslinux.cfg file and reboot. That being said, someone mentioned in a previous comment that in Backtrack 3 you could use the UUID of the device in the changes statement. It does not appear that this is currently working for Backtrack 4 or at least we haven’t got it working yet. Will keep you posted if we can get it to work.

Hello Guys. I have a question. Hope this will make sense. I have a Backtrack 4 in a USB thumb drive and i can use it on my computer (laptop), but why is it i can’t use it to other computer(laptop). Does it requires any setting on a certain computers or do i have to download some software on their computer in order to use it. Hope you can help me.

Thanks – Rixon
