First a bit of bg info:
I dont usually have windows xp, in fact I pretty much dont outside of school, and I dont even have computers class in school anymore so hey.
My iPods firmware died, and after ages of googling, I found rockbox, an alternative, open source firmware. This all worked grand, until I tried to update that and I can;t get the newer version working

Now I can use my dads laptop for a few days while he's away on business, so Im wondering, if I use windows to format the iPod, then when I can get the lappy use the iTunes 7.4 restore tool will it a) bring the iPod back to the original functioning firmware and b) fix the bootloader so that it loads the iPod firmware by default?
