Advice Request Why is only one of my Windows OS working

[Lettuceface]

So every time I boot up my computer only one Operating System works. It offers me Volume 3 Or Volume 2. I always have it to default to volume 3 but that completely stopped working and black screened before login. So I changed to volume 2 and now it works and lets me go to login and go to desktop just fine. I was wondering if this has happened to anyone else? I've cleaned my pc and unplugged unnecessary things. Nothing is wrong with my displays or connection. Just now Windows Operating system volume 3 doesn't work anymore. Some articles say there should only be one OS but I don't know how to get that. And I am scared I am going to delete the working one and get stuck with the broken one. Idk...Any ideas?

So you have two Windows installations, are they installed on the same drive, that has two partitions or two
separate drives?

Something similar happen to me, I have Windows 10 installed on one SDD and Windows 11 on another SSD.
At boot up, I had to select either Volume 2 or Volume 3, and it would load either OS.

After Windows 11 did an update, I could not boot into Windows 10 anymore. The solution was to remove
the Windows 11 SSD from my system and my Windows 10 booted up fine.

You can also try disabling one of your drives in your BIOS. Provided you are using two different drive for the OS installs.

If your computer is supposed to be a simple, straightforward setup, with a single version of Windows as your only operating system, then you might consider running the Macrium Reflect Boot repair tool, in order to fix your booting issues.

If you have a multi-boot system, and all of your operating systems are Windows, then Macrium Reflect Boot repair tool should be able to handle that, too. You will be presented with an option to choose the default or primary operating system for the boot process.
