Solved Corrupted OS on multiple drives?

I have multiple storage systems on my PC:

• 2TB M.2 (where I keep my OS and install games)
• 250GB SSD (I use it for sensitive data)
• 2TB HDD (I use it for personal media)

When some years ago I built a new PC, I purchased the M.2 drive brand new and formatted the old SSD and HDD to recycle them in my new PC as secondary spaces to store my stuff.

For reasons I never really questioned myself about, everytime I turn my PC on, before accessing my M.2 automatically, it always lets me choose which OS to access.
Which is weird as I'm a bit ignorant on the matter, but since the screen lasts literally 1s before it automatically access my M.2 OS, I never really dwelled on it too much.

Lately I've been having problems, and a super kind and generous helper ( @phillpower2 , Administrator from the Support Team - he's extremely helpful and kind ) from this very same forum told me in another thread that there are several installation errors on my PC after analyzing my Speccy data. And since he told me to try and fresh-install my OS on the SSD and keep it there for the OS alone, for the first time after years I tried to access the other two available OS options.

These are the results:

This is the "Choose an operatin system" screen that appears everytime I turn my PC on and lasts approximately 1-2s only ⬇️



This happens after trying to access OS n.2 from the list ⬇️



And this is what happens after some longer loading for accessing the OS n.3 (which says it resides in Volume 7 and I have no idea what/where that is) ⬇️



Needless to say but best to clarify, if I choose to access OS n.1, it just automatically logs into my PC regularly.

Now, can someone tell me what this all means?
I never installed any OS ever on my other disks, yet it seems like I have some corrupted leftovers of Win10 on both of the ones I don't use for my main OS?

How do I clear the corrupted part without compromising my personal data?

Thanks for the answer Phill, it's good to have you here!

Here's the screenshot you asked me to provide:

the problem that you have is that we have no idea and there is no way of finding out which other two partitions belong to the working version of Windows and in this instance Windows 11.

Sounds very unhealthy for my PC.

Well, since I wanted to follow your suggestion, format everything and isolate my OS into his own SSD island alone to work properly and peacefully, I guess this is all the more incentive to take two birds with one stone.

Guess what's left now to correct this mess is:

1. Backup data & format the 250GB SSD;
2. Install Win11 OS in the 250GB SSD;
3. Make sure everything works fine with the new OS now installed in the SSD;
4. Revoke Win11 product key license from M.2 ;
5. Clean format fully the M.2 ;
6. Set up the SSD to be the first to boot in BIOS Utility;

This way I should be able to boot my PC with my SSD's OS that now becomes the C disk automatically and leave it for the OS alone, while better using 2TB M.2 (should be faster?) for games and the 2TB HDD for sensitive data/folders/files etc.

Is that correct?

Hello, Phill!

Concerning this issue, I suppose I just solved everything by back-upping my sensitive data away and just hard formatting every other disk.

I now installed the OS in the 250GB SSD and I followed the whole correct procedure you suggested:
MOBO drivers>Storage Units drivers>GPU drivers>CPU drivers>Windows Updates

We can mark this thread as closed if you'd like, I'll give you my final response update on the HD Camera issue's thread.

Thanks for your support!
