Was able to
1) make USB with Mojave in Legacy mode
2) install on SSD - the BIOS is set to Legacy and SATA to ACHI,
3) set up Mojave
4) run MultiBeast.
5) remove USB and reboot! That's the problem area.

When rebooting I get error message, "no bootable drive".

When I re-insert the bootable Mojave install drive, the Clover Bootloader is recognized, and system works

I see "5102, booted from EFI" at bottom right of screen.


The Black bootup page with Clover on top gives me following
1) "External" - which is the USB
2) APFS - "Boot FileVault Prebooter from Preboot"
3) APFS - Boot MacOS Install from Preboot
4) APFS - Boot MacOs from MojaveSSD
5) "Recovery"

If I select #4 - it boots up just fine, but I need to have the USB in the computer.

It works but annoying because I used MultiBeast, which I thought loaded the Clover Bootloader onto the MojaveSSD.

Can anyone help, as I'm pretty sure it's just a matter of getting Clover onto the SSD properly.

I realize the USB indicates "EFI" - but it was compiled using Legacy, so my BIOS is in Legacy Mode.

thanks!
