I installed Linux from one bootable USB thumbdrive onto another bootable thumbdrive. That works. However, now my Macbook Air boots to "error: no such device: XXXXXXX...
grub rescue>". If I hold the Option Key, I can boot to OSX. I have a CarbonCloner backup of my OSX build (created after the grub error) and I can boot from it.
Is there a simple way to remove grub and return my mac to just running OSX as intended? I only want to run Linux from the thumbdrive.
Many thanks from a newbie.
