In my case, I have a Hackintosh PC (Sierra 10.12.6, mobo Gigabyte 990XA-UD3, CPU FX-6300, 8GB RAM, graphics card AMD Radeon HD6770 1GB replaced recently by Gigabyte Nvidia GT730 2BG because it’s metal compatible, disks with Windows 10, Windows 7, Ubuntu 20.04 as 2nd OS on the Windows 10 disk (UEFI) and 2 installeation of Manjaro Linux -1 on a separate SSD disk and 1 as 2nd system on the Windows 7 disk-) and I wanted to boot the Manjaro Linux system that is installed as a 2nd system on the Windows 7 disk which was partitioned as legacy disk (MBR partitioning) from Clover.
There are some interesting info on booting Linux from Clover (in case someone has a Hackintosh and other OSs on various disks) in these articles: article 1 and article 2
