[all variants] USB flash drive doesn't boot anymore

view full story

http://ubuntuforums.org – I have previously used USB flash drive to boot various distros, during which time I had Ubuntu 10.04 installed. But recently I wanted to install other distros and check them out that way. And then I wanted to dual boot Bodhi Linux and openSUSE 12.1, which failed miserably. openSUSE didn't appear in the GRUB and after fiddling with the graphics drivers on Bodhi it too didn't want to boot. So after many fails at "reviving" Bodhi, I decided to delete it and openSUSE and install another distro. It ended up being Fuduntu. In the end i was not satisfied with it and i tried to make a bootab (Hardware)
