I created a bootable USB drive which works as expected, but it creates a bunch of obscure files cluttering up the main storage space of the flash drive. Will it still work if I put these boot-files in a sub folder?
Also, is there a way to put multiple bootable images on 1 flash drive but be able to select which one when in the BIOS? For example, if I wanted to create a flash drive bootable version of Ubuntu and Acronis Rescue Media, 1 one physical flash drive, would this be possible?
