Cannot Extend Volume to Merge Unallocated Disk Space on the Same Drive

Question

My primary Windows drive has 93.15 GB of unallocated disk space that I am attempting to merge, but the extend volume option is grayed out. Since I have data on my primary drive, I do not want to format it. How do I allocate this disk space that hasn't been allocated?

Accepted Answer

First, we need to figure out why the extend volume option in Disk Management is grayed out.
