I want to do a format & reinstall Windows XP on my htpc, which does not have a cd drive. It's a small mATX case and a real PITA for me to get remove my dvd drive and get it in there just for this task ...

I've been doing some reading about installing xp from a usb flash drive... it seems doable, but overly complicated. I'll go this route if I have to, but I have another idea. Hoping yall can tell me ...
