I too am getting a new boot entry on every single restart, on a Gigabyte H110M-A. I'm a little perplexed, though, because I only have a single hard drive, with only one EFI partition and only one bootloader (Clover). It seems like I'm in the minority here.
Is it possible that the Apple Recovery partition is messing things up? If so, is it safe to wipe that partition? Here's my diskutil dump:
#: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Mac 999.3 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3
Hmm. Perhaps you would be brave enough to try that out? It being your idea and all.
Mostly just the linux dd command can backup, wipe, and restore your recovery partition. It should be pretty simple:
# backup partition dd if=/dev/disk0s3 of=disk0s3_backup.dump bs=1m # wipe partition (delete it) dd if=/dev/zero of=/dev/disk0s3 bs=1m # be sure to use fdisk / sfdisk / gparted to backup & restore partition table entry too # or use dd to backup the first N megabytes including the partition table dd if=/dev/disk0 of=disk0_first_N_megabytes.dump bs=1m count=N # reboot a bunch of times # see if it worked # restore partition back to where it was dd if=disk0s3_backup.dump of=/dev/disk0s3 bs=1m
You should still have the USB key handy too in case anything else goes wrong (can't boot).
