Shifting from BIOS to UEFI with the Windows 10 Creators Update MBR2GPT disk conversion tool
Do you have the same problem when running MBR2GPT from WinPE? Chances are, you have something running in the full OS that is causing the issue and this is why it is recommended to run MBR2GPT in WinPE.
I was finally able to complete the process.
I did this through the OS, not in PE.
The issue is really with how the process went on my SSD.
It was analyzing it for a while, like a good hour.
But, before the last time I tried it, when it worked, I used the Defragmenter tool to "optimize" my SSD, then it did the same thing, but now it worked. I can post the logs if it is going to help anyone.
I did have a boot problem, my BCD was effed up.
For this I did you WinPE and had to do the assign a letter to the EFI partition, then do the bcdboot c:\windows /s e: command to get the BCD stuff from the installed windows to the EFI partition, now it boots and switched the GPT so all is well.
