Unable to convert basic volume boot disk to raid 0 boot disk

XY Problem:

I was running out of space on my 256GB SSD Boot drive. I have several other drives that are mostly full and take up all my SATA ports. I bought a new 4TB drive to move some stuff over from my Boot drive, along with a SATA PCI card to add some more SATA ports.

After installing the PCI card to get more ports I discovered that I had an extra ssd that was previously used as raid 0 for my boot drive in the past and that I must have undone that at some point. I decided to try to make my boot drive RAID 0 again.

Thus began my troubles. (So my problem is that I want a RAID 0 drive as my boot drive.)

I used a backup program (partition wizard) to copy my entire SSD over to the new 4TB drive. I then wiped the boot drive and set up firmware raid in my BIOS (MSI Click 4). I booted into the 4TB drive, then used partition wizard to copy the drive back over. The copy succeeded, but I couldn't boot into the boot drive anymore (inaccessible boot device BSOD). I read that RAID results in different bcd data, so that I might need to install Windows first and then copy stuff over.

I made a Win 10 installer usb, installed Win 10 Pro on the boot ssd raid array. Then I was able to successfully boot into the drive, but of course, it's not really a replica of what I had, it's a new install. I boot back into the 4tb drive, and use partition magic to wipe the ssd data partition (not the system reserve partition), and then I copied over just the logical partition to the boot drive logical partition. This is where I might have messed up. I wasn't sure if I need to copy as primary or as logical, so I did logical.

Now I can't boot into either... attempting to boot into the 4tb gives

Your PC/Device needs to be repaired
The application or operating system couldn't be loaded because a required file is missing or contains errors
File: \Windows]system32\winload.exe
Error code: 0xc000000e

and attempting to boot into the SSD fails with Inaccessible Boot Device.

I tried to reinstall windows again but now get a Driver PNP Watchdog error and the install fails. It seems my system is borked. I have all my data backed up using a backup service, so I'm not too worried if I need to start anew, I just really don't want to. I'd rather recover the volume if possible.

Unsure of what to even try from here. I know there are a bunch of bcdboot commands I can run, but when I tried to set the boot drive partition as active it gave me The specified partition type is not valid for this operation, hence why I think I set it to the wrong type.
