I made a partition to change over, but now what?

So I watched Michael Horn’s video about switching from windows to bazzite, and I created a new partition to put my data in. I’ve installed bazzite but now I have to get rid of this old partition. The internet told me I needed to use a tool like Gparted, so I used that to get rid of the old partition. But when I look at my drive properties in bazzite, it still says the drive is 200gb smaller than it’s supposed to be.

What am I missing?

I’ll guess that even though you removed the old partition in gparted, you didn’t expand your Bazzite one. If that’s the case, here’s another video that might help:

He uses gparted in Mint to modify the partitions, but you can use whatever you used before. Hope that helps.

Thank you. I actually got it sorted now, using the command

sudo btrfs filesystem resize max /var/home

Cheers
