I have some unallocated partition that I want to merge with my partition containing Windows (nvme0n1p6). I don't want to lose the data in Windows, but as long as other partitions are unaffected, I am OK with losing Windows data if that is my only option.
GParted:
I read that merging when not adjacent is hard, and I couldn't find a proper solution online.
