Need help undoing a partition

Alright, I started with a 80gig hard drive. This was my first time I've ever partitioned a hard drive. But because I wasn't careful I made a big mistake, I made the partitioned part of my hard drive the active partition. Because of this windows failed to boot up, anyway I fixed the problem by installing windows on a separate hard drive and fixed the problem.

However I wasn't able to delete the partition that I made (It was something like 20gig). So now I'm stuck with a 60gig hard drive and I'm not sure how to fix it.

Here's a screenshot:

Hello? Can anybody help me? It would be appciated

 

Senzuri:

You should be able to fix this with Acronis Disk Director (DD). If you want to enlarge your C drive to incorporate the 17.9 GB of free space, then do the following:

1. Start DD
2. Right-click on your C partition
3. Choose "Resize"
4. Drag the handle on the extreme right side of the graphic to enlarge the C partition. Don't move the data within the partition, just enlarge it. When you are finished check that the unallocated space before is zero and the unallocated space after is zero and that the partition size is the maximum possible.
5. Click on the checkered flag to commit.

This will give you back the maximum partition size for the C drive.

 

Thanks for the help k0lo, although I think I tried your idea but I was unable to enlarge the C partition. This is what I did:

It seems I can't select the unallocated partition, what should I do?!

 

Senzuri:

I see the problem. You have DD set on Automatic mode. When you start DD the next time, set it to manual mode (on the view menu) and then follow the steps in my previous post.

Don't use the "Increase Free Space" wizard. This wizard was designed to increase the size of one partition by decreasing the size of another. You don't want that.

 

Awsome, it worked! Thanks a lot k0lo
