Step 3:13, what it does it dump a RAW dsdt of your system, you can then patch it and compile it. If you already have a working one, you could skip it.
Booting issue...when you boot without the USB, does Clover boot loader starts?
If not, you did not install Clover correctly. Install it again and then copy the EFI folder over from the USB.
If Clover loader appears with the USB but will not boot, then you might be missing the EFI custom files that needs to be copy over from the USB.
