Installed new GPU, can no longer boot onto NVMe drive.

I have Windows 10 on my NVMe, even upgraded to 11 to test it out before reverting, that was a month ago. Two days ago I bought a 6700 XT to upgrade. I installed it, loaded my pc up, was on my NVMe drive and everything was working out fine. I wanted to clear the old GPU drivers off of my machine so I went into Safe Mode and went through the process of removing them with DDU. The first wipe I chose to do was to wipe out any old AMD drivers. After I rebooted, I cleaned the Nvidia drivers. This is where the problem stemmed from. As I loaded my machine again, I quickly discovered my boot drive had switched me to an older drive I was using for storage. I unplugged everything but the NVMe and I haven't been able to boot its OS since then.

The W drive is the one causing issues.

My BIOS is using its latest patch, the NVMe can still be used, I can open files on it right now from this drive, but I can't get it to boot the OS.

I've taken a few screenshots of the BIOS and there's something that doesn't make sense to me about it.

There are two Windows Boot managers on the drive. When I try to boot into them, I get mixed messages about what's happened to my drive. The first message I see is of a blue screen with two error codes, depending on which loads first.




These are the two I see. I can hit f1 all day and it will bounce between the two.

From everything I've read in the last two days, my only option is to reinstall the OS, right? If there's another option, I'd love to try it first.

If you have a backup in Macrium and have a recovery USB you could go to UEFI and in the BOOT settings put USB as the first priority.
Then you put in the recovery USB from Macrium and the PC will boot from that.
A menu will open up, it is slow so you have to be patient, and in the menu you should be able to find the backup image you have stored on an different drive, an external or USB. Those have to be plugged in of course.
Pick the image you want for restore and choose your OS drive to restore it to.
It will take about half an hour.

If you are not able to make the recovery USB to work, you could do a clean install of windows, download Macrium in the new Windows and then get access to your backup image you have store on a different drive and restore it.

Macrium is able to restore image that have been made of older version of it self too.

I think it might be because I renamed the drive to W in Disk Management but I'm not sure.

I have the USB installation already set up, but no backups.

"..the NVMe can still be used, I can open files on it right now from this drive, but I can't get it to boot the OS."

You could get another old drive and install Windows on that drive, and then copy some files from the NVMe.
It is offcourse dependent of what kind of files it is, but games should work I guess and the bookmarks and favourites from the browsers too.

So when you have done all that work, you could clone it back to the faster NVMe again.

Can I do that without a product key? It's been so long since I've installed Windows on anything. I bought a drive to do that already but I wasn't sure if I should clone the drive or install a fresh Windows onto it. I wanted to clone it to see if the same exact problem would arise or if it's specific to the NVMe.
