MBR2GPT Disk layout validation failed - Last partition too close to the end of the disk.
I am trying to convert my drive from MBR to GPT as I am trying to enable AMD's smart access memory. However, when attempting to use the MBR2GPT tool in cmd, it reads: My setupact file reads the following: ESP partition size will be 104857600 Info MBR2GPT: Validating layout, disk sector size is: 512 bytes Error ValidateLayout: Last partition too close to the end of the disk. Should end at offset 1000204869120 or below, found at 1000204886016 Error Disk layout validation failed for disk 1 These are the disk's partitions as seen from disk management: The error message suggests that the last partition should be shrunk, as it ends "too close to the end of the disk." However, the last partition is the recovery partition, which the disk management application will not allow me to shrink. I have tried shrinking the (C:) partition in the middle by 200mb, 500mb, 2gb, and even 16gb. None of these changed the error message at all. I have spent hours searching for a solution, or even just more information about this specific message and how people have fixed it, but unfortunately I have only seen people fix it by shrinking their partition, which hasn't worked for me. Any help would be greatly appreciated.
Problems with partitions when using MBR2GPT
I'm not sure how to proceed to prepare for Windows 11. When running mbr2gpt, I get the following: C:\WINDOWS\system32>mbr2gpt /validate /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 Here's my disk layout: I got to this point thinking I needed to delete the Recovery Partition. It now is the 861MB Unallocated partition. What should I do to prepare for a successful run of mbr2gpt? My system is as follows and is running Windows 10 Pro 21H1: AMD Ryzen 5 5600x, 32GB RAM, Asus Tuf Gaming Pro X570 Wifi The OS being used (C Drive) was a clone of that on the G Drive. The intent of the clone is to provide a backup and to move the OS from a smaller drive to a larger, newer one.
