Transferring or Restoring WIN 10 system on an new WIN 11 computer

Look for the drive letter that contains the Windows 10 drive that you are trying to convert. You will also need the disk number:
diskpart
list disk

So, let's say that the Windows drive you are trying to convert is on volume E: and the disk it is on is disk 1. The command would then be:

E:\Windows\System32\mbr2gpt /validate /disk:1

if it passes validation the command would then be:

E:\Windows\System32\mbr2gpt /convert /disk:1

I've booted from an installation USB.
list disk shows Disk O 489 GB (100 MB free) and Disk 1 28 GB
Steve108 thought the drive would be X
So, I tried this cmd line, using X:\Windows\System32\mbr2gpt /convert /disk:0
I got a list of '?commands? like ACTIVE . . .
I don't think windows is active.
Can I start over, with the MBR SSD installed as a passive drive, but run the mbr2gpt from WIN 11 running?

Why not try my method first? /disk: would be /disk:0. You did not post the results of
Diskpart
List volume

Sorry, I missed the 'list volume'
Here is a photo of the screen with list disk and list volume

So, what is the result of:

Code:

E:Windows\System32 mbr2gpt /validate /disk:0

?

From the command line DISKPART> with either of these four, I get nothing but the list ACTIVE . . . :
E:\Windows\System32\mbr2gpt /validate /disk:0 or
E:\Windows\System32 mbr2gpt /validate /disk:0 or
E:\Windows\System32\mbr2gpt /validate /disk:1 or
E:\Windows\System32 mbr2gpt /validate /disk:1

Aren't you booting using the USB flash drive?

Please display these additional command results:
sel dis 0
det dis
lis par
sel par 1
det par
sel par 2
det par
sel par 3
det par
sel dis 1
det dis
lis par
sel par 1
det par
exit


Were you not able to boot the internal disk drive?



Please post images of the BIOS settings:
Legacy
UEFI native (without CSM)
UEFI hybrid (with CSM)




Can you use command prompt at boot?

You don't run mbr2gpt from Diskpart. You run it from a command prompt. In the screenshot you posted you would run it from:
X:\Sources>

not from Diskpart>

To get back to the command prompt from Diskpart, enter the command:
exit

YES!! I followed your instructions with Source> E:\Windows\System32\mbr2gpt /validate /disk:0 WAS VALIDATED, then
E:\Windows\System32\mbr2gpt /convert /disk:0 CONVERTED!
I rebooted (without USB installation disk, of course) and my WIN 10 system worked!
I then disconnected the WIN 10 SSD, re-installed the NVMe EFI-GPT drive, and it works.
Next, I want to learn how to do a dual boot, with the NVMe WIN 11 and the WIN 10 SSD. I suppose I should re-post the question on the Windows 11 Forum forum? Thanks, NavyLCDR. You're a great tutor.

Dual booting Windows is easy. Under normal circumstances when you boot into Windows, the other Windows installation will get a drive letter assigned to the partition it is installed on. Let's say it gets drive letter E:. Open a command prompt with admin privileges ("run as administrator") and the command would be:
bcdboot E:\Windows /d /addlast

Just change the E:\Windows to match whatever drive letter the other Windows installation gets.
