Resizing Garuda partition using unallocated space from windows in dual boot

This is a very common process, in a few words/steps (but you should be searching for the details in internet).

  • Login from a live USB and open KDE Partition Manager or Gparted, if available.
  • Unmount both windows and Garuda partitions.
  • Reduce the windows partitions and assign the relevant unallocated space to the Garuda partition and confirm.
  • Login to Garuda and:
  • Resize/extend the btrfs filesystem with sudo btrfs filesystem resize max /
  • Perform a full btrfs balance with sudo btrfs filesystem balance start /
