Windows 7: Extending an OS partition

Extending an OS partition

Hey guys,

I dual boot with Win 8.1, and I recently moved my 8.1 installation to a larger SSD. I cloned the drive from a 64 GB drive to a 120 GB SSD using Macrium Reflect, but it didn't extend the partition to 120 GB when it cloned the drive. I am now left with ~57 GB unallocated on my Win 8 drive, and Win 7 won't let me extend the partition to use the whole volume. It says it can't because it's an OS drive.

Is there some way (or software) to do this, or do I have to clone it again and use some sort of setting in Macruim?

Any help is appreciated.

Here's the screenshot. The drive in question is disk 0. (Drive M: )




Drive H has had the partition deleted, but it came back for some reason. I have to delete it again. I want to extend drive M to use the entire disk.

I have deleted the partition on drive H. This is what it's supposed to look like:

You can extend the partition using Disk Managment. Partition or Volume - Extend
