Hello everyone,

I managed to get Sierra up and running on my Asrock Z77 extreme4, I52500K and Geforce 970.

I have installed clover on my Sierra drive and selected;

"Install for UEFI booting only" & Install Clover in the ESP"

When I set my Sierra drive as first boot in the bios I'm getting the following message;

"Reboot and select proper boot device or insert boot media in selected boot device and press a key."

diskutil list

/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *250.1 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS Sierra 249.2 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3

/dev/disk1 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *15.5 GB disk1
1: EFI EFI 209.7 MB disk1s1
2: Apple_HFS USBboot 15.2 GB disk1s2


Disk 0 is the SSD where I installed Sierra on.
Disk 1 is the USB where I boot and installed Sierra with.

In the bios when my USBboot in inserted in the USB slot I see UEFI USBboot, but on my Samsung SSD drive there's no UEFI in front it. I'm guessing I missed something and it doesn't see the drive as a correct boot?

I tried google and found quite a lot of topics, but so far none of them worked.

Any ideas from the gurus here? :)

Thanks!

Thank you for the response!

The second option is working perfect! At first it didn't worked, because I choose my USB instead of my HDD drive.

Shell> map fs*➝ Show all partitions

Shell> fs0: (or fs1: or fs2: ...)➝ Switch to fs0, fs1, fs2,... partitions
Shell> ls ➝ List the contents of current partition / directory
Shell> cd \efi\boot ➝ Change the directory to \efi\boot
Shell> ls

Then:

Shell> help bcfg -b -v ➝ Get help onbcfg command
Shell> bcfg boot dump ➝List current boot options
Shell> bcfg boot add N bootx64.efi "Clover" ➝ Add bootx64.efi from the current dir (\efi\boot) as a boot option labeled "Clover" (You will see this name also in the UEFI BIOS Boot menu boot items). N is the boot option number: 0 if you want it to be the first, 1 to be the second, etc.
Shell> bcfg boot dump ➝ Check if Clover is added
Shell> reset ➝ Restart the system and load Clover from SSD / HDD
