I have a Windows XP laptop with no built in CD drive and a corrupted operating system. I tried making a bootable DVD with a iso file and installing it with an external DVD player, but the old laptop doesn't seem to work with the DVD player. When I try to boot and hold F8 only the original copy of Windows comes up as a boot option. Next I want to try installing that .iso to a USB flash drive so I can boot directly from that. How can I make a bootable Windows XP flash drive from an iso image?
