I've allocated half of my SSD for Windows and the other half for KDE. Now that I've set up everything on KDE and I want to remove the Windows partition, I've unmounted and deleted it using KDE Partition Manager. What's the next step to merge the unallocated space into my ext4 partition? I'm using Kubuntu 25.10, and the unallocated space is located before the nvme0n15p segment on my SSD.

Check if the unused partition is located to the right of your active partition. If it is, you can just right-click on the ext4 partition and select 'Resize' to expand it into the unallocated space. If the unused partition is at the beginning of the disk or if there's another partition creating a gap, it will be a bit more complicated.
You'll need to boot into a live image and use tools like GParted or KDE Partition Manager to expand your ext4 partition. Be aware that the disk has to be offline while doing this, which is why the live environment is necessary. Remember to back up your data first, just in case!
If I go the live image route, will it keep all my current OS data? Also, I noticed all my hard drives are under /kubuntu2510/media/username/. Is that going to be an issue, or should I have them mounted higher up?
