5.2 Add Clover as a boot option On Aptio, it's not enough to rename Cloverx64.efi on HDD to BootX64.efi to enable it to start (see here). But it seems that's what you need to do on Gigabyte Hybrid EFI. Standard procedure for adding an OS boot option in UEFI is to add boot option variable to NVRAM - that's what is needed on Aptio. Boot options can be managed with bcfg command in a shell. But, this command is available only in UEFI shell (shell2) and since shell2 requires UEFI 2.3 or newer, users with older UEFI have a problem. If you are the "lucky" one with older UEFI where shell2 does not work, try with my modified shell2 from here. This is not fully working port, but bcfg works and I'm using it only for boot options manipulation with bcfg. Users of UEFI 2.3 or newer can put shell2 to FAT32 USB stick as /efi/boot/bootx64.efi and just use this one. Since I need old shell for normal use and moded shell2 for bcfg, I have old shell set as /efi/boot/bootx64.efi and moded shell2 as /shellx64.efi (in the root of USB) - in this way I can press F8 during POST and choose "UEFI: stick name" to load older shell or press Del to enter UEFI Setup screens and then select Exit/Start shell to load moded shell2. Actually, I have both shells copied to HDD EFI partition and added as separate boot options, but that can be done later. Boot into shell2 (real one or moded) and find Cloverx64.efi on HDD EFI partition with some combination of the following commands: > map fs* > fs0: (or fs1: or fs2: ...) > ls > cd \efi\boot > ls And then: > help bcfg -b -v and try to understand help from the screen > bcfg boot dump to list current boot options > bcfg boot add N cloverx64.efi "OSX through Clover" to add cloverx64.efi from the current dir as a boot option labeled "OSX through Clover". N should be boot option number: 0 if you wan it to be the first, 1 to be the second ... > bcfg boot dump to check if it is added > reset to reset the system and to try to load Clover from HDD When it is added, reset the system and press F8 during POST (or whatever key is needed to get selection of boot options) and "OSX through Clover" should be there. Select it and try if it works.
