Hi Fred
welcome to the forum. I noticed some of your other posts, but don't understand why you are against installing to hard drive. You mention defrag, but that should not be a problem as you sould keep your XP defragged anyway. You also mention your data, but you should have backups anyway, at least one backup of stuff you would prefer not to lose, and at least two backups of stuff you really really do not want to lose. The only thing left now, I think, is Windows XP, but you should have an installation disk for this, unless you have one of those hidden restore patitions. You should also have drivers handy, e.g. for motherboard. A computer can fail at any time, and you can lose everthing on it. It is my opinion that you should be able to get up & running again, assuming the hardware to be OK, in the time it takes to do a fresh install. Partitioning is so simple when you don't have to worry about loosing stuff, but you should never be in that position to begin with.
Good luck with which ever method you choose, and enjoy you stay here.
