I had 64 bit Vista and needed 32 bit Vista for some school applications so I had my brother help me out and partition my HD. He only set me up with 20GB on this new partition and I'd like to extend it so I can throw FFXI on there. Now, I've read up and it seems like it should be pretty easy (Disk Management > Expand Partition) but I'm not able to choose that option. After some research, it seems like I can't extend that partition due to its location. The original partition is labeled D: and the new partition is C: and I believe this may be the problem. But I'm pretty noobish when it comes to this so I was wondering if my assumption was correct? Also, what can I do to help alleviate this problem?
I study on my laptop for 3-4 hours each day so wiping it and starting over probably is not an option right now. I don't want to risk messing up and losing time studying. Any tips/help is appreciated. Thanks!
I've attached a screenshot of my HD partitions to help illustrate my point.
