Returning back to the root of the problem, can you give a bit more light? If you have an USB with ext2 (or whatever), you can not boot a new BIOS, correct? If you have an USB with FAT32, and with the exact same filesystem (except ownership and permissions) that the USB with ext2 has, you can boot it? The question being, can you make a USB bootable just by switching the filesystem? And a thing I just came up with: does your ext2 USB have the "bootable" flag set on its boot partition? -- Svi moji e-mailovi su kriptografski potpisani. Proverite ih.
