After MBR2GPT receiving "Failed to update ReAgent.xml, please try to manually disable and enable WinRE."

Hey all,

I performed a mbr2gpt operation which failed with the following log.

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 0
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!

Disk partition looks as follows after the operation

Running reagentc /enable fails manually.

I had missing Winre.wim file which I copied over from a windows 10 iso to c:\Windows\System32\Recovery which produced no impact.

I am suspecting the initial unnamed partition before C: could be a source of the issue? What can my next steps be before I try to reboot my computer to try to enable SecureBoot and then hopefully upgrade to Windows 11.

Thank you all!
