Drive letters seem to have been swapped about

Hi,

So a week ago I left for travels and shut off my PC, Windows 10 informed me about some updates, I told the system to update and then shutdown, which I assume it did. ( Not sure, I left, had to catch a plane)

Anyway, I come home and it won't boot properly. It will give me a 0xc000021a error, tell me it is gathering info and will reboot ( which it never does)

So I have tried
repair the system --> no can do
to do a restore -> it can't find restore points
boot in safe mode --> same blue screen
fix the startup procedure --> no success

So then I thought, screw this I'll do a reset --> can't find enough free space.

That could be possible the OS disk is a fairly old small SSD (120GB), so I went in to the command line to see if there was anything to remove there. At which point I notice something weird.
When going to C: it looks a lot like my old D: drive, D looks like the old F, E seems to actually be the old C drive where the OS is installed, F is my old G drive ( the second SSD) and G seems to be the old F drive. ( although I am not entirely sure about which one was F and which one was E)

So went into DISKPART and listed the volumes and sure enough, going by the disk sizes it is now

C -> 1TB
D -> 1TB
E -> 120G
F -> 500G
G -> 1TB
H -> 450M ( hidden partition, I assume the recovery part ?)

And it should be along the lines of

C -> 120G
D -> 1TB
E -> 1TB
F -> 1TB
G -> 500G

Anyway I suspect that something has messed up here somehow and that this is why the system nor any of the recovery options want to work, I think windows is looking for files on c:\ but not finding them there.

So my question: is my suspicion correct and how do I fix this without totally breaking everything.

So it finally does boot?
If you can get into Disk Management....that is where you can change the drive letters.

Well no it doesn't boot into windows, it boots in the windows recovery options when I press F8 before the windows logo appears. So I really only have access to the commandline from there. So I guess I am asking how I can fix the drive letters from there ( and if that sounds like it's my problem)

Maybe try this.

Well I put all the letters back to normal, closed the command line and rebooted --> same error
Went back to the troubleshooting interface and cmd from there and all the drive letters were back to their scrambled self -_-

Anyone with a suggestion?

I might be doing a clean install at this point as I don't know what else you would do. ...although maybe someone else does.
