Merge non-contiguous partition on Windows 10
Solution 1:
From the comments, it sounds like:
- It can't be done with Windows' built in Disk Management tool.
- The de facto solution is "just use GParted", which is free, open-source, and cross platform.
The suggestion to delete the recovery partition using the built-in diskpart (more here on how to use DiskPart to remove the recovery partition) command line tool worked for me, so in this case I ended up not needing to worry about non-contiguous partitions.
