  1. Worked like a charm. Have been trying to clear out GRUB from my HD for a while. Will bookmark this page for future reference. Thanks!

  2. The first command resulted in the error message of “read-only filesystem”.
    So my first command was:
    cd /Volumes

    And the rest worked like a charm. thanks!

    1. I would be careful mounting it under /Volumes.

      In particular, I would be afraid that by doing so, the Finder might see it and start writing stuff to the EFI partition (e.g. a .Trashes folder, .ds_store files, etc.). I’ve read reports that this can corrupt the EFI partition, rendering your Mac unbootable, forcing you to wipe the drive and reinstall from a backup.

      If “mkdir mnt” didn’t work, then that just means your current directory is read-only. A simple “cd” command to move to your home directory first (so EFI gets mounted under /Users/username/mnt) should be sufficient.
