Hi. Sorry if this is in the wrong place - But I am having a bit of a problem with partitioning. As far as I am aware, Windows 7 needs 16 gigs to install, so I figured I would partition my hard drive to dual boot it and Vista. Whenever I try to partition 20 gigs (4 more just to be safe), it won't let me. I can only partition 12. Any help would be appreciated. Thanks.
