To keep things simple, you should only have your SSD boot drive plugged into your computer, plus your UBS drive. Sometimes the smallest change can break your build, so having a backup will help you quickly return to the last working configuration. And always MAKE BACKUP COPIES after each successful change you make, especially changes to your ist file. ** ALWAYS MAKE BACKUP COPIES of your original files and folders, and put them in well labeled folders (say, on your desktop).

Whether it works or not, I hope it will help familiarize you with a few basic things, like how to identify and mount the EFI drive, where the most important files are, and one approach to troubleshooting settings in Clover Configurator. It worked for me, but I don't know if it will work for you. This is a description of how I fixed my build. Please read this through at least once before starting, to make sure you understand the steps, and have everything ready when you need it. Hopefully you still have a backup copy of your original El Capitan EFI folder (or at least your original ist, inside it). I made the same mistake when I first started out I'm still working on the GUI section, but have otherwise been able to copy over all other previous sections of the ist, so this will just be a finishing touch instead of a show stopper.'

'I finally relented to doing it the hard way: copying over the EFI directory from the USB to the EFI directory on my SSD, then slowly adding back settings section by section to the ist file, saving and rebooting each step at a time. In my Naivety, after reading your solution the 1st time - I literally copy pasted the EFI directory folder from my USB to my SSD where the folder was located and hit 'Replace' I though that would do the jobīut basically I need to understand how you did this. I checked 'About This Mac' and everything seems to be alright there - even my Graphics card is showing (Though it shows 2048MB, whereas it is in fact 3GB but nevertheless it's showing the right name, company, etc.) - The problem is with the bootloader on the SSD.Īs of now, I have ZERO knowledge of how to operate the CLOVER CONFIGURATOR (but I can learn, if you can send me a link to the tutorials), I dunno how to mount the EFI directory nor anything about editing the ist (Though I could locate it inside the EFI directory folder - both on my SSD as well as the Installation USB stick) Yes, you got the last part a 100% correct. Hi, Thank you so much for the quick reply. I'm still working on the GUI section, but have otherwise been able to copy over all other previous sections of the ist, so this will just be a finishing touch instead of a show stopper. (I had a bunch of custom functions and custom names, etc.). It seems obvious now but the problem was with the GUI section of ist, where you specify unique settings for the boot loader. I finally relented to doing it the hard way: copying over the EFI directory from the USB to the EFI directory on my SSD, then slowly adding back settings section by section to the ist file, saving and rebooting each step at a time. I tried updating all of the kexts, but it didn't fix boot problem. The implication is that there was something right with the EFI directory on the USB stick that wasn't right with my previous EFI directory.

After a lot of problems with the initial installation, it kind'uv worked, but I could only boot up via my motherboard's boot menu on startup, before the BIOS splash screen (and selecting the UEFI USB stick).īut I couldn't boot up from the SSD without the USB.
