    After which OS should be recovery partition put then? do you need 2 RE for each like in screenshot from OP?
    I normally disable the recovery environment using "reagentc /disable". Then delete the recovery partition. Then re-enable the recovery environment with "reagentc /enable". This puts the recovery environment files in a hidden Recovery folder right on C: drive. My multi-OS disk will have an EFI System partition, MSR partition, followed by the partitions containing the OSes. No recovery partitions.

    NavyLCDR, on previous Windows versions (7 for sure) Recovery folder was under C:\Windows.
    Do you know why did M$ moved it to a dedicated partition on Win 10?

    No clue. Although, maybe, it has something to do with more partitions being available with GPT disks than MBR disks. And it's even more confusing because when you disable the recovery environment, Windows 10 "stores" the files in C:\Windows\Recovery (I think). But then when you re-enable the recovery environment it moves it to C:\Recovery. Here's the transcript of deleting a Recovery partition:

    I don't know if this is the problem but you seem to have 2 RE partitions, which one should Windows use?
    Can you boot into RE? (blue screen Recovery Environment)

    Btw. you can't have 2 Windows OS'es on same drive I think. (unless I'm wrong ofc, never tried with GPT)
    I have had 2 Windows OS'es on same drive for several months now. Now the default won't boot and the system boots directly to the RE environment where I choose the second OS and it opens and runs.

    @Brentg,

    We need to start with seeing the output of:

    Code:
    diskpart
    select disk 0
    list part
    DISKPART> select disk 0

    Disk 0 is now the selected disk.

    The commands that you want to try first are:

    Code:
    diskpart
    select disk 0
    select part 1
    assign letter=w
    exit
    bcdboot C:\Windows /s W: /f UEFI
    exit
    Reboot the computer, see if that fixes anything. If it boots into C: then run the command:
    Code:
    bcdboot F:\Windows /d /addlast
    That will set up dual booting.

    In your BIOS, make sure that CSM (or legacy BIOS) booting is disabled. You have to boot in UEFI mode. Make sure your disk 0 is the first disk in the boot priority list. If you have an option called Network Stack or PXE, disable those - that is booting from a network location.

    The command assign letter=w worked, but when I ran bcdboot C:\Windows /s W: /f UEFI I got the message that the boot files could not be copied.
