Hi,I can't convert it from MBR to GPT.
This is the error:
MBR2GPT: Attempting to validate disk 0
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
Disk layout validation failed for disk 0
I Just resolved the validation issue.
basically you must not have more than three partitions and not any free space left on the hard drive.
if you check the list of partition on DISKPART you will see that even the free space is listed as a partition.
you can use tools like disk manager (built-in windows) or minitool to resize the current partitions to take up the left over free space then validate mbr2gpt again.
hopefully it works for you too :)
let me know
