I have Vista on my laptop (Dell Inspiron 1525) and I want to dual-boot Windows 7 with it. However, I have the maximum number of partitions: I have a 180 gig partition or so for Vista and all my files, a 10 or so gig one for Dell's recovery feature, and two unidentified partitions. One of them is 2.5 gigs and the other is less than 100 megs. I think the 2.5 gig one is Dell MediaDirect, but deleting that partition would cause some major damage to my laptop should I accidentally press the MediaDirect button on my laptop while it's off. Still, what would that less-than-100-meg partition be? In disk management, both unnamed partitions are shown as 100% empty. What can I do so I can make a new partition with my unallocated hard drive space and install Windows 7?
