Problems with partitions when using MBR2GPT
Hi Bob Arthur
As I can see from the screenshot, following points seems pretty good for disk 2:
- There must be a maximum of three primary partitions in the MBR partition table
- You should not have any extended/logical partition, all three partitions must be primary partitions.
- You must have active partition on disk 2
The following requirement is missing on disk 2:
- There must be a system partition (OS Partition)
Please have a look and let me know your feedback.
Thank you for responding SalmanAhmed! I very much appreciate your willingness to help.
So mbr2gpt is attempting to convert the original C drive (now G) and not finding an OS partition, even through Windows is installed on both the current C drive and the original C drive, which is now the G drive? I had thought it was going to change the disk with the OS currently being used (with the C and E partitions. That is why I was trying to delete the System Recovery for that drive, to get Disk 1 to three partitions.
I was moving to the 1 TB drive to make more room for the OS, but see that it has somehow filled up. I'm not sure how that happened but I suspect it may have to do with MS Flight Simulator having been installed (although the majority of its files should be on the E drive.You're most welcomeBob Arthur ,
I've just noticed that there is no target disk specified in your mbr2gpt command, please execute as below in elevated (Run as Admin) mode in cmd:
mbr2gpt /validate /disk:2 /AllowFullOSHere it is:
C:\WINDOWS\system32>mbr2gpt /validate /disk:2 /AllowFullOS MBR2GPT: Attempting to validate disk 2 MBR2GPT: Retrieving layout of disk MBR2GPT: Validating layout, disk sector size is: 512 bytes Cannot find OS partition(s) for disk 2
