Im once again trying to create a bootable USB Pen drive with XP on it, but no having much luck The problem is - I run petousb and format the pen drive, which works fine. i then run multiboot and select the target source, but im now constantly getting the error message ' USB is no FAT FAT32 or NTSF and is not valid' but i HAVE formatted the drive with FAT and NTSC but still no joy. Its worked before but refuses to now! HELP PLEEEEEEEEEEEEASE! Any help welcome! Thanks Gareth
