Hi, I have a problem booting from my BT5 live USB.

All of the obvious things seem to be ok:
  • Using the latest Backtrack ISO (64bit)
  • md5sum is correct
  • I can boot Linux Mint from the same USB, no problem with that
  • I have checked the boot order is correct
  • I've tried UNetBootin, LinuxLive USB Creator, and a couple of others to make the USB bootable.

But when I try to boot from the USB, it goes straight to the HDD's boot selection screen. If I remove the HDD from the boot order, leaving only USB, it just goes back to BIOS setup.

Does anyone has any ideas for what might be the problem here? Thanks.
