You only need to do Option #1
Convert Windows 10 from Legacy BIOS to UEFI without Data Loss
Doh. That's what I thought so I tried it again and got this:
C:\Windows\system32>mbr2gpt /convert /allowfullOS
MBR2GPT will now attempt to convert the default book disk.
If conversion is successful the disk can only be booted in GPT mode.
These changes cannot be undone!
MBR2GPT: Attempting to convert disk 1
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
MBR2GPT: Trying to shrink the OS partition
MBR2GPT: Creating the EFI system partition
MBR2GPT: Installing the new boot files
MBR2GPT: Performing the layout conversion
MBR2GPT: Migrating default boot entry
MBR2GPT: Adding recovery boot entry
MBR2GPT: Fixing drive letter mapping
MBR2GPT: Conversion completed successfully
Call WinReReapir to repair WinRE
MBR2GPT: Failed to update ReAgent.xml, please try to manually disable and enable WinRE.
MBR2GPT: Before the new system can boot properly you need to switch the firmware to boot to UEFI mode!
C:\Windows\system32>
Seems to have worked, but I don't know what that last part is under "Call WinReReapir to repair WinRE".
So now I have to restart the PC and disable CSM? I'm not sure where I would switch the firmware to boot to UEFI. Where would I find that in the BIOS?
With the command prompt still opened as Admin, type:
reagentc /disable
reagentc /enable
...one at a time
Then, you'll need to reboot the computer... enter the BIOS and disable CSM.
Then... enable Secure Boot
Then hit F10 to save and exit the BIOS
THEN... the PC Health check should say you're OK.
Ok, I entered the lines as you said and got this:
C:\Windows\system32> reagentc /disable
REAGENTC.EXE: Windows RE is already disabled.
C:\Windows\system32> reagentc /enable
REAGENTC.EXE: Unable to update Boot Configuration Data.
C:\Windows\system32>
Don't worry about it. Do this...
Then, you'll need to reboot the computer... enter the BIOS and disable CSM.
Then... enable Secure Boot
Then hit F10 to save and exit the BIOS
Then right click and extract this .zip file to a New Folder on your desktop, and run: WhyNotWin11.exe
WhyNotWin11.zip
Ok I restarted, disabled CSM and enabled Secure Boot in the BIOS. I was a little apprehensive about that file you posted, but I got it and ran the thing. It was kind of funny. I thought it was going to be some joke script or meme saying ":Why do you want Windows 11?" Lol
If you get all GREEN boxes, like this.... you're good to go...
If you DON'T get a GREEN box for TPM version, go back into the BIOS, and in the Tweaker section...
enable AMD CPU fTPM ....then F10 to save and exit.
Then... run WhyNotWin11.exe again.
From your computer specs, that should be all you need to be Win 11 compatible.
For anyone else reading this, these instructions are specific to his motherboard and Windows installation.
