MBR2GPT issues

[foxtrot26187]

So I recently upgraded my GPU/CPU and am trying to make use of ReBar on my AsRock B450m Pro4.

I've done the leg work and my Win 10 is running in Legacy mode. I attempted to use the tool the traditional way offline but it cannot locate my OS partition, cannot convert disk 0. I noticed however under disk management that disk 0 is set to my Crucial 1 tb SSD, not my Sabrent 512 m.2.

Disk 1 does have the ability to 'Mark as Active Partition" but I am very hesitant to go messing with all that and lose my ability to boot. I know enough to navigate around my mobo and do entry level changes like this but I'm not too advanced.

Can anyone help me get this fixed up so I can make the most of my new gpu?

For clarification, my 512 gb set as my C drive is my boot drive, so Disk 1 should be the one being recognized, not 0. Disk 1 aka C is labeled as Boot, Crash, Dump, Primary Partition., w/499 MB of recover partition.

Drive 0 has one partition of System Reserved, 50 MB (System, Active), with a separate partition as E, 931 gb, page file, primary partition.

Are you able to boot to windows without the Crucial drive connected? Does the conversion tool run without that drive?
