I've already saved everything I need (mainly e-mails) to my USB drive. My primary drive is partitioned with XP and Linux Ubuntu in a dual boot. When I do a "custom" Windows 7 install will it only wipe the XP partition or will it wipe the entire hard drive and set it to one partition? I'd prefer it wiped out everything as the grub loader is kinda screwed up on my system anyway. I have the newest Linux version on another box so it won't be a loss for me to start clean again on this one.
