Hi guys, need a little help. I disabled VT-d, CSM and everything that could interrupt booting. I set my bios to see UEFI devices but it only sees my USB, and yes I copied EFI folder to EFI partition. The thing is, I don't have Windows installed, so I can't use EasyUFEI, is there something else I can do? Please help.
 
What OS did you use to format and partition the hard drive you'll be installing to ? Does the drive already have anything on it ? What is most important is that you can boot from the USB into macOS recovery to be able to format and partiition the drive with Disk Utility. Do you get that far ?
 
I used Disk Utility to format my SSD, and I am currently using MacOS that's on it, but can only boot into it with USB.
My problem is that after installation my BIOS doesn't recognise EFI partition on my SSD, so I need to boot with EFI from USB..

Is the EFI folder on the SSD an exact copy of the EFI folder on the USB ? You don't need to boot the SSD from the BIOS only from the OC bootloader GUI screen.
 
You haven't mentioned the macOS version or the boot loader that's installed.

It's most likely that you did something wrong in Disk Utility. Maybe you didn't select APFS Format when you erased the SSD ? Did you make the scheme GUID ?

macOS would have converted the drive to APFS anyway on installation :)

best for the user to click on view, show all devices and the erase the entire drive

then after installation, mount EFI partition and then copy over entire EFI folder over

This was done already. OP says it's the exact same EFI that's on the USB that does work.
