    Can your method be used to remove the first and second "Windows Boot Manager" below?
    I assume only the third one, Windows Boot Manager (P1: ST500DM002-1BD142), is needed.

    Hi there
    I don't bother with things like EasyUEFI or similar.

    I'm not sure either about "Dual BIOS" !!!!

    However in general the rule if you do need to "multi-boot" (although these days why not use VM's (Virtual Machines) the best or most common advice is to install the Windows system(s) first.

    Then when installing Linux OS'es at grub install time grub usually on most Linux install scripts will propmpt if it should search also for other OS'es so at boot you'll see Windows and Linux as GRUB starts.

    cheers

    I don't need to "multi-boot" and install Linux.
    I just want to remove the superfluous "Windows Boot Manager".

    Same here, I do dual BOOT with W10 Insider but this one doesn't do anything.

    Will the following remove the two unwanted "Windows Boot Manager"?

    BCDEdit /delete {562f5072-413a-11eb-bfdb-e0d55ecc65a3}
    BCDEdit /delete {562f5078-413a-11eb-bfdb-e0d55ecc65a3}

    I just ran the above commands. The two unnecessary "Windows Boot Manager" entries have been removed from the boot menu.

    The following photo was taken before I ran the commands.

    Is this working for all computers, or the ID is specific to your hardware? How do I find out which is the ID for my computer? I want to remove a MacOS entry back when I was experimenting with MacOS Mountain Lion

    Find the specific identifier by running the following command:

    BCDEdit /enum firmware

    Unfortunately this doesn't work for my case (legacy setup, not UEFI). I will download latest Strelec or Windows 10 PESE and boot in UEFI mode. Then I will use EasyUEFI to hopefully get rid of any unwanted entries.
