I downloaded the daily test ISO image for Saucy and used Unetbootin to create a bootable USB stick. I do this fairly regularly with no problem. Today all of a sudden, it won't work. I get this error after rebooting:
I've googled this and there are some old, outdated threads where people seem to have "fixed" it with no real solution. In one case, someone had a corrupt file. I checked the MD5 and it's good. In another case, someone removed the drive and re-inserted it when the screen showed the Xubuntu splash but that didn't work for me. I formatted the thumb drive to FAT32 and tried again. Still no dice. The machine is an IBM Thinkpad T60, 32 bit.
