    Windows never touched the main EFI entry in my cases, even at updating it from 10 to 11, and I clarified it 3 times.

    With a few Google queries we may find it mentioned, yet I’ve just found a weak one at this moment:

    If you are booting with Windows, you should simply be aware of the problem, because you can easily overcome it by temporarily changing the type code of the non-Windows ESP(s) if you run into problems. Note that Windows will boot just fine on a disk with multiple ESPs; it’s just the installer that chokes on such disks.

    Some documentations found mentioned relatively similar:

    The only Microsoft supported workaround for booting multiple installations of Windows in a uEFI environment is to use a dual boot configuration. This will make use of a single ESP and one MSR while still allowing the user to choose to boot to an installation on disk 1 or disk 2.
