MBR2GPT Disk layout validation failed
When i try to run
mbr2gpt /validate /disk:0 /allowFullOS
i get the following output
MBR2GPT: Attempting to validate disk 0 MBR2GPT: Retrieving layout of disk MBR2GPT: Validating ...
Please go throw the below steps:
- There should be a maximum of three primary partitions in the MBR partition table, including 100MB system partition as mentioned below:
1. (System, Active, Primary Partition)
2. C: (Boot, Page File, Cash Dumps, Primary Partition)
3. 😧 (Primary Partition) - You should not have any extended/logical partition, all three partitions must be primary partitions.
- If you have more than three partitions, you must delete the least important partitions after backing up the important data.
- I have done it successfully (Screenshot Attached)

- SalmanAhmed Outstanding help. Clear and organized. Fixed my problem. Now have my EVO SSD running as a GPT boot drive. Cheers!
Thanks! It worked for me!
Must have 3 or less active partition. (unallocated space is no problem)
Hi YvesVA,
I'm glad that the above information was useful for you. Please do not hesitate to contact me for any further assistance, I will welcome the questions you may have.
received validation failed, read all 3 pages of posts since i'm doing this on production vm in business. Disk had 4 partitions, 1 boot, 1 system (c:) and 2 recovery partitions. Shrinking c: by 200mb didn't work. Deleting last partition (recovery partition) did work. Thanks. Not sure if it was too many partition or not having free space at end of drive.
