So I just made a quick test that shows the problem must be with some GRUB configuration. I booted into my USB stick from a friend computer. Worked fine. I then ran update-grub, restarted the PC and could no longe rboot from the USB. What should I change on grub.cfg? I look at it but don't see anything suspicious.
