Hi, I have a harddisk of about 500Gb. Due to the upgrade from Vista to Windows 7, my recovery partition (13Gb) was gone. After fiddling with the diskpart command, I managed to convert this to unallocated free space. I can create a new drive of this 13Gb, but I'm unable to add it to my C: partition or (this is what I'm planning) creating a bigger partition (around 25Gb) for an other OS. I would like to do this in Windows itself, since I'm not really good in partitioning and don't want to end up with an unusable system. So, to sum up, this is the problem. 1) I cannot extend my C: drive with the unallocated space, also not possible when it has a drive letter assigned 2) I cannot create a partition (let's say, D: ) of 25Gb, using the 13Gb unallocated space. When shrinking my C: partition, the unallocated space is created after the C: drive, leading to this scheme: Unallocated -- OS Partition (C: ) -- Unallocated And I can't merge them with the built-in GUI of Windows 7. Any (unrisky) suggestions?
