Reclaiming an un-used partition

Some time ago I partitioned my drive and I now have 4 separate partitions,I no longer use one of these partitions which is currently set as drive E: and I would like to claim the space back and add it to my C: drive.

I have tried going through some of the tutorials that are online but can't seem to work out how to complete the process.

I would appreciate it if someone could walk me through this process.

When I originally partitioned the drive I used Easeus Partition manager.

Can you post a screen shot of Disk management?

Disk Management - Post a Screen Capture Image

You can use Disk Mgmt to extend C once you delete E:
Partition or Volume - Delete
Partition or Volume - Extend

OK thanks,,,I was gonna try that but got a little worried in case I would never see the space again.
Will be trying to attempt this operation tomorrow so if I have any problems I will give you guys a shout again.
Hopefully I won't be needing to..and if I don't then I will say Thanks for you help with this matter in advance.

It should go fine. Post back a screenshot so we can see Disk Mgmt after youre done.
