Hi guys, first-time poster here, looking for help. I have the same issue as juststeev, with the "NOT FAT FAT32 or NTFS Format and is NOT Valid" error on USB_Multiboot 10. Tried several different USB drives, formatted them to FAT/FAT32/NTFS, didn't work. Also tried the trick with putting fsutil.exe next to the USB_Multiboot_10.exe file. Still nothing. And finally I've also run FIXPATH, which showed up nothing, and made no difference! What am I doing wrong??! Is it just that I'm on Vista but trying to work with programs that deal with XP? Help!!!!
