On Acronis True Image, there is a button to make "rescue media". I've used this successfully to make a CD and I've also tried to use this option to make my USB flash drive bootable with the Acronis True Image utilities. Although files are being copied to my flash drive, I can't seem to get any USB-bootable computer to boot from this flash drive. The wizard kept talking about floppies so is the compatibility between what a computer needs to see with a floppy the same as what it would need to see with a USB? Ultimately, how can I make a USB bootable flash drive? thanks.
