hi friends,
A quick request for help on something that has been driving me crazy. I successfully installed El Capitan (11.3) a while back on my NUC 5i5, with windows 10 dual boot, and it works great. However, I cannot and have never been able to boot into my OSX install using the Unibeast USB -- booting from Unibeast USB and selecting boot the OSX install on my internal hard drive always fails. Booting verbose, I see that the boot process is losing connection/communication with the USB drive somewhere during the boot process, giving the cannot find 'root device' error. I tried the recommended solutions to this: different Unibeast USB drives (2 different USB 2.0, 2 different USB 3.0), a different USB port (both ports on back, both ports on front), a USB 2.0 hub, a USB 3.0 hub. Usually this isn't a problem, since Clover on internal drive -> OSX on internal drive works fine, but since I dual boot, whenever Windows decides to load updates and reassert its boot loader in EFI, thereby bypassing clover, I can't boot OSX anymore.
My solution to this has been cumbersome -- either boot from Unibeast USB to the OSX Installer on Unibeast USB, open terminal, and use terminal to mount the EFI partition, and then use the command line to rename EFI/Microsoft/Boot/bootmgfw.efi to bootmgfw-orig.efi and then copy cloverx64.efi from the clover/boot folder to bootmgfw.efi in the Microsoft/Boot folder. This works but is always slow, and there are other reasons why I might need to boot into my OSX install on the internal disk using the Unibeast USB. Has anyone run into this, or know how to fix it?
Configuration notes: internal drive is Samsung 950 Pro NVME, both Unibeast USB and internal drive have the nvme driver kext in their EFI partitions; USB drives tried were Adata 64GB usb 3.0, Sandisk 8gb USB 2.0, Corsair 8gb uSB 2.0, another Adata 64gb USB 3.0 (with Unibeast); failure to boot into internal OSX from Unibeast USB occurred before I began dual booting, when it was just OSX.
Thank you so much in advance. Take care and happy hackintoshing!
