Windows 10: MBR2GPT

Good afternoon folks.

Windows 10 was installed on the Legacy mode MBR of my PC. Now l want it on the UEFI mode such that my pc can boot from it.


From my BIOS, my pc is on both Uefi/Legacy mode and l want it on UEFI mode only without reinstalling windows.

My version of Windows is 2004


Please l need help.


Thank you.

:)

Your computer is already booting in UEFI mode which means the drive is probably already in GPT format. What makes you think it isn't?

What does diskpart, list disk show?

 

MBR2GPT

I also think so.

Windows upgrade 1903 automatically created a 450 mb recovery partition which I had to delete as mbr2gpt don't work with more than 3 primary partition.

So, do I need to create a recovery partition now to get mbr2gpt work?

I have already tried what you told. It says something like "can't enable win re service "

Thanks for your feedback Andre.

The link below contains a video I was using to try and convert my MBR to GPT on my system drive..

https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gpt

The video explains that the methods used in your suggestion will destroy data and that is why the new utility MBR2GPT is the recommended solution. Since this utility is new with the latest Fall Creators Update, it may need updating. I hope someone has more
experience with it and can shed some light on why it fails for me.
