>I'm currently at about 1GB free so space will need to be made no matter what, just wondering how much I should budget for.
I'm thinking you might be borked right there, and you may as well salvage whatever data and do a clean reinstall. On a bigger disk. For xp pro I'd budget minimum 10G, and maybe 20-30G if you're putting all your apps, games etc on there as well.
Well I'd rather not, but if it's the only way then I'll go for it. I might use the WinClone thing or just copy all my stuff over to my PC and install a fresh Windows.
Either way, I'm probably going to do it slowly. I have the lazies.
