Argg Win XP makes it difficult lol on 95 and 98 you could make a boot disk with system files and then just copy over FDISK and stuff.. but if you try that with a MS DOS startup disk from win XP you get Wrong Dos Version.

I'm seeing if I can figure out another solution for you. If someone dosn't present one before hand. I tested it and just uploading the files dosn't work because there are hidden files that even Show hidden files in windows dosn't show.. I assume they are hidden in the boot sector or something.
