Hi all, I just got Catalina running great on my machine with Unibeast, but obviously would only boot 'via' my USB installer, & not via the system drive alone

I then tried using MultiBeast (after doing that Sudo trick show on this threadto allow it to work in Catalina) in order to boot directly from the system drive

Obviously didn't tick the correct boxes, & now Catalina wont boot...even when going via the USB boot loader first .

Is there any simple way to remove the bootloader that Multibeast added to my system drive? Or Do I have to install Catalina again from scratch?

If it helps, I also have Ubuntu & Win10 on separate boot drives.

Cheers !
