I have an HP Pavilion with a 298GB Hard Disk partitioned in the following order:

Partition 1 is about 119GB with Windows 7 on it
Partition 2 is D: drive 60GB
Next partition is 10GB free space
Last partition is C:Drive Windows 10

I want to delete Windows 7, leave the D: drive and then combine everything so that I just have C: and D: drives.

Any suggestions would be appreciated.
