Problem with Live USB

[Cabs21]

Hi, I am new to Backtrack and wanted to try to install a live USB version on to a Kensington 4gb flash drive. Following the instructions on this site for installing Unetbootin to create the Live USB did not work. After Unetbootin finished installing Backtrack 4 final and was successful I rebooted, changed my BIOS, rebooted with the thumb drive in place. The laptop instantly found the thumb drive and began to boot to it. This is when the problem hit. I always come to a black screen with the word Boot: at the top left and a flashing cursor. No matter what I type the same response appears. After a few seconds the computer shuts down and then turns back on. It does not simply reboot it shuts OFF for a good 2 or 3 seconds. Anyway this is my issue right now. I have an HP Compaq 8510w Mobile Workstation (Here are general specs CLICK) running Ubuntu 9.10. I would like to have a Live USB version of backtrack instead of running vbox or partitioning my drive. Thanks for the help.

Make sure your thumb drive is formatted to the correct file system, ext3, or redownload The ISO and install to your thumb drive again. you could also make a bootable cd if you have any blank DVDs

Yes, l believe the partitions have to be done like this:

mkfs.vfat /dev/sdb1
mkfs.ext3 -b 4096 -L casper-rw /dev/sdb2

[mine are sdb1 and sdb2 Yours might be different].
