Next steps I did on my last hackintosh were install Clover Configurator to mount the hackintosh EFI, back it up, and update it with the functioning one from your boot flash drive. I still keep it just in case an update breaks the bootloader.

Yeah I have numerous copies. They're useful if the first one fails of course but also to try out updates of bootloader software or settings tweaks.

But I really don't understand why people make their OS drive their boot drive. Besides the potential for catastrophe it also means you can't move the OS drive between machines or do OS drive backups freely.
