MBR2GPT cannot find os partition

Turn Drive C: into System.

Run the following command as administrator:

bcdboot C:\Windows /s C:

You may have to mark Disk 0 Partition 1 inactive, remove Disk 0 or change the disk order for this to take effect. Also Drive C: needs to be marked active.

 

MBR2GPT: ValidateLayout: Too many MBR partitions found, no room to create EFI system partition.

Please see "Disk Prerequisites" in the following article:

MBR2GPT - Windows Deployment | Microsoft Learn: https://learn.microsoft.com/en-us/windows/deployment/mbr-to-gpt

Excerpt from that article:

Before any change to the disk is made, MBR2GPT validates the layout and geometry of the selected disk to ensure that:

• The disk is currently using MBR
  
• There's enough space not occupied by partitions to store the primary and secondary GPTs:
  
  • 16 KB + 2 sectors at the front of the disk
    
  • 16 KB + 1 sector at the end of the disk
    
• There are at most three primary partitions in the MBR partition table
  
• One of the partitions is set as active and is the system partition
  
• The disk doesn't have any extended/logical partition
  
• The BCD store on the system partition contains a default OS entry pointing to an OS partition
  
• The volume IDs can be retrieved for each volume that has a drive letter assigned
  
• All partitions on the disk are of MBR types recognized by Windows or has a mapping specified using the /map command-line option
  

If any of these checks fails, the conversion doesn't proceed, and an error is returned.

You may need to delete one of the Recovery partitions on Disk 2.

 

MBR2GPT Error - Frustrated

I think those steps will fail because mbr2gpt is looking for a system partition, which you just deleted previously.
