installing windows on macbook

[lixi]

I just bought my macbook (80gb) and wanted to partition 10gb to windows. i installed windows xp - an old version apparently - and then needed to install an updated windows installer and service pack 2. the windows installer had no problem but i couldn't finish installing the service pack 2 because an error keeps popping up saying there's not enough space in my C:\ drive and needs 4mb more spore. But when i check my harddrive space it says there's still 7.6gb free and the sp2 doesn't take up that much space does it? I can't install bootcamp unless i have sp2 installed, so i'm at a catch 22. Please help!
