partitioning - How do I shrink an Extended Partition in Vista?


I'm trying to shrink some partitions on my laptop so I can dual boot another OS, and I need about 6GB of space to do this.


Unfortunately when I got my laptop and trashed the default Vista install, I didn't think ahead about this and I ended up making an Extended partition in the free space, and I've been using it since then.


I've managed to already shrink it by nearly 12GB, but I can't then create a primary partition in the free space because it seems the extended partition wants to remain the allocated owner of this space.


I was hoping I could get somewhere with diskpart but I got as far as shrinking the same volume another 6GB (and hence it is now 12GB).


My question is: can I unallocate (shrink) the Extended partition so I can create a primary partition, or do I have to remove the extended partition so a primary partition can exist in front of it?


Answer



I only rarely use it, but it seems like something that GParted could do from the Live CD. It may even be specifically addressed in http://gparted.sourceforge.net/larry/resize/resizing.htm
