I need to merge two BTRFS partitions on my main disk without bricking my computer since I messed up while installing a couple months ago since my laptop was used from a printing company that used windows 7 on their brand new windows 10 laptops (ugh), because I have been putting it off and now I have 2.2GB left on my small partition, I think I can transfer the files from my other partition after merging with sudo
My last two attempts (on other machines) havent worked out
You cannot do any merging on a linux mounted file system and not brick it.
Boot off the install medium (or any current Linux bootable) and use gparted to delete the unwanted partition and then add it to the btrfs partition.
let me know if I’m just being stupid or not, but what about data on both partitions?
I have important things on both partitions. So like do i use a USB disk for holding files in case something gets deleted while I repartition?
If you have important data you should back it up before doing major partition changes. Generally these things work but some times things fail and data is lost.
You do not have to delete the partition if you shrink it and leave space for the other partition to grow into.
It does have to be adjacent to the partition to grow it (except if you used LVM)
The only way to “merge” two filesytems is to copy data from them to the “merged” filesystem (which can also be one of them if it has enough space). It is completely independent of the question “can I merge two partitions”.
Save data on some external medium, repartition your disk, restore data back.
