Hi, I need to upgrade to Windows 11, but have run into the issue of all of my drives being partitioned as MBR. When trying to run MBR2GPT to convert the drives, the validation fails. I believe this is because I fumbled the upgrade from Windows 7 to Windows 10 and now have two "System Reserved" partitions, one on Drive 0 and one on Drive 3. My BOOT drive is on Drive 3 currently. I will attach a screenshot for context. Can I get a step-by-step guide on how to clean this up and properly convert the drives to GPT? Thank you very much.-Trevor
