I have been trying over the last few days to boot from a bootable usb pen drive on my Compaq dc7600 Small Form Factor desktop PC so I can dual-boot, but to no avail. The pen drive contains Ubuntu 12.04.3 and I have double checked it on another PC (of a different model) and it IS bootable. I have changed the BIOS boot order and selected the option to boot from usb, but it will not boot from usb.

My current BIOS version is Hewlett-Packard 786d1 v01.03 (outdated, possibly the problem?) and I am running Windows XP Professional SP3.

So what I need to know is:

  • Do I need to change some other sort of BIOS setting?
  • Do I need to update the BIOS?
  • Boot from some other media?
  • Something else?

Help would be much appreciated.

Thanks in advance

Update: I have just updated the BIOS to version 1.61. Does this help my situation?

Did you checked your USB port? –  Renju Chandran chingath Sep 18 '13 at 5:02
I have tried all of the usb ports on the machine –  Levi Sep 18 '13 at 7:09
I have not yet tried to boot from a disk, but I want to actually see if I CAN boot from usb. A disk will just be a fallback option if that fails –  Levi Sep 18 '13 at 7:22
