    I did a windows update on my secondary Win10. When I did that, I lost access to my main Windows 10. I only got it back by restoring an image I made weeks before. Currently I can access my main Windows 10 but the moment I run an update on my secondary partition and do a reset of it, I will lose boot access to my primary Winwdows 10

    After you do an update on your secondary partition or a Reset, open a CMD window as administrator and type:
    diskpart
    List disk
    select disk n (replace n with the windows drive number, it's probably 5)
    list part (take note of the "primary" Windows 10 partition letter)
    select part 1
    assign letter=W
    exit
    bcdboot X:\Windows /s W: /f UEFI (replace X with the primary Windows 10 partition letter found with list part)
    diskpart
    select vol W
    remove letter=W
    exit
    exit

    you can use this: 10_22h2_4-23.zip

    copy the recovery folder into your windows\system32

    it will replace whatever is in there now.

    then open admin cmd prompt and type:

    reagentc /enable

    After you do an update on your secondary partition or a Reset, open a CMD window as administrator and type:

    bcdboot driveletter:\windows

    (replace driveletter with the primary Windows 10 partition letter that you can see in explorer or diskmgmt )


    bcdboot defaults to the current boot mode and system partition. Allocating letter to system partition and use of switches not needed in this scenario.

    I don't know which Win10 uses the 515MB drive
    if the recovery environment is enabled, reagentc /info will tell you the location :

    For what I know, on a Win 10 dual boot from same drive, only one Recovery partition is used. @SIW2 can confirm or deny.

    I've been able to get each Windows partition to have it's own RE environment without needing a WINRE partition. Now each install has it's own Win Re environment within its partition
