Hey all.... Right now I have 2 partitions on my iMac. One 260gig for OSX and the rest for vista (must have fallout 3 & FSX). Bootcamp works great as is. I would like to be able to install another version of OSX onto a small (40gig) partition to play around with it. When I go into disk management to create the new partition taking the needed space from the main OSX partition area, it tells me my bootcamp partition may become unbootable if I proceed. Is this true? I though on macs we could always shift around partitions with relative safety. I'm not wanting to change the size of the windows partition. Im just stealing some from OSX side.
