I was using LVM on an arch install disk and typed
pvcreate /dev/sda2 but that was where my Windows installation was located.
Did it overwrite the whole disk? If not, how can I revert it back to a working version?
Note: I don't have a recent backup of a working filesystem so that's not an option.
EDIT: I just recently backed up the broken partition so that if I mess with it I can try again.
