Open Core quad boot 2 MacOS and 2 windows

[blg]

hi all, trying to get open core to quad boot on same drive Mojave, Monterey, windows 10 and windows 11.

The 2 Mac OS versions work as expected (as macOS always does)

it is kind of working but I only have one windows icon in open core. This single windows open core icon then goes to the microsoft boot loader with the 2 windows versions to pick from which then successfully boots ether windows version.

I want Mojave because I need 32 bit software still. I want the 2 windows versions because I do not have enough faith or experience with windows 11 yet to abandon windows 10 until I know 11 can be relied on.

Perhaps I’m being pedantic but ideally I would like 4 icons to choose in opencore.

Any suggestions would be much appreciated.

thanks
Brett

Which is to be expected since Windows will add itself to it's own boot manager when another version is already installed.

You'd have to install both versions on separate disks with all other drives disconnected so that no existing EFI partition with the Windows Boot Manager or anything else is visible.
