My Recovery Environment and DualBoot Menu Are gone. Please Help!!

Hello, due to my love of 3D gaming, I have to have two seperate Windows 10 installations. One Installation is supposed to have the latest updates and drivers and the other one is supposed to only be at either Windows 2004 or Windows 20H2 to maintain compartibility with old drivers for 3D Vision.

My problem is that I can only reset my computer in the Windows 2004/20H2 partition and not the other install. And when I reset that 2004 partition, I lose access to my dual boot menu. When I do try to reset my primary everyday partition, it tells me "no recovery environement found"

This is 2023, I'd like to think I should be able to run dual installs of Windows 10 and be able to reset either one if I have an issue. Can anyone help me fix my recovery for both installs so that I can reset either install without it disabling my dual boot menu?

Is drive H: the other Win 10 partition?
Drive 6 doesn't have the MS reserved partition.
Did you merged two drives into one?

Do you want to do a Reset or a Repair install?
- Reset your PC prepares the PC for recycling or for transfer of ownership by reinstalling the OS, removing all user accounts and contents (e.g. data, Classic Windows applications, and Universal Windows apps), and restoring preinstalled customizations to their factory state.

- Repair install of Windows 10 by performing an in-place upgrade without losing anything other than all installed Windows Updates.

Hi, drive H is the other Win 10 partition.

I did not merge two drives into one. What I originally did was create 3 partitions. One for my main Win10, second for my older Win10 and third for Apps.

I installed my older Win 10 (drive H) second and someway somehow it became the one with the recovery environment. This was on 1809 until an unprompted upgrade to 2004 then 20H2. THis created a reserced partion of 563MB that you see. I don't know which Win10 uses the 515MB drive

What I want to to do is to reset my 20H2 partition so I can start fresh. I have been getting some driver crashes. But when I ran the reset option, it disabled my dual boot menu. So that's problem 1.

Problem 2 is that just to test my ability to reset my primary Win10, it "can't find a recover" environment.


I would like to be able to reset both WIn10 partitions. AND be able to have access to my dual boot menu if I do that. @Megahertz

to test my ability to reset my primary Win10

not clear from your posts if you can boot into your primary win10

if you can:
boot into your "primary win10" and enable winre

at admin cmd prompt type
reagentc /enable
(then press enter)

You didn't answer my question: Reset or a Repair install.

@meghertz, I think I did or maybe I didn't understand. I wish to reset my main Win10 partition. I want to clean it and start afresh.

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
