Well since so many people recommend btrfs because “it have never lost any data for me”. I want to suggest OP to never use btrfs ever. Because it has lost my data, at least three separate times, the most recent time a week ago. And it’s not because of a power loss or anything, it just corrupted my files for absolutely no reason at all.
Stay away from btrfs at all costs.
I think you mean std::move
Looks like you messed up the partition table. Try scandisk, it may be able to find your partitions.
That was you! I remember this.
Out of curiosity, what GPU do you have?
