A few days ago I "uninstalled" MacOS High Sierra because I didn't use it anymore, there were some 51MB worth of unallocated space, which I think is Clover. I have uninstalled MacOS COMPLETELY in the past, but there is some residue in the boot menu list, an entry that says "UEFI OS" which was created by Clover. But even if I wipe out the entire disk and clear the CMOS data, it is still there. How can I remove this?
