I have prepared over a dozen USB thumb drives with various Linux distros only to have each of them fail to successfully boot.
Some of the techniques I have used:
- I have verified the integrity of the iso images that I have downloaded (pgp signatures, hashes, etc).
- I have used GParted to format with Fat32.
- I have used Unetbootin to "create" the bootable disks from iso images that I already had on hand.
- I have performed "builds" of the OS's onto the USB drives per official OS documentation.
BIOS appears to be able to boot from USB...
When the boot sequence finds the USB device, I receive an error message, something to the tune of "Boot Failed ... name_of_USB_drive "
I'm quite unsure as to why I have such results. Do any of you have input on the matter - if so, what is it? Thank you for your consideration.
