Need Help with MBR2GPT

Hello,
I'm running ver 2004 in legacy BIOS mode & trying to move to UEFI
The \validate completed OK once I reduced MBR partitions to 3 (from 4). Then ran the \ convert and got the following:

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!
PS C:\WINDOWS\system32>

I'm lost as to what I should do next? Any help would be appreciated.
Best,
Mike
