Computer strangely went into Repair Startup Loop after trying to boot from sleep mode today

[omonoiatis9]

I've been looking all over the internet for the past few hours.
The "start windows normally" option obviously didn't work.
It asks me to go into startup repair. That does not work either and says "cannot find root problem" and asks whether to send info to microsoft or not. Then I try some commands from the command prompt from the system recovery options page

Now here is the weird part: I ask it to list all my disks and volumes. I have 2 hard drives on my computer, however it only lists one (my primary one, which is also larger and a newer model).
My secondary hard drive is about 6-7 years old. I am not sure on which drive I had windows installed. Could it be that the old drive failed today when I tried to boot back from sleep mode and windows happened to be on it, and that's why I'm running into this?

I also ran a chkdsk c: /r /f /x on the disk that was detected. No problems to be fixed found. System restore/system image recovery are also not possible. Windows memory diagnostic came back fine too.

UPDATE: I managed to get out of the startup loop, however this now happens every time I try to boot from sleep mode (might actually happen on every single boot, didn't try booting from a full shut down yet). None of the command prompt commands I tried did anything, nor the startup repair itself did anything. I just clicked "shut down" from the advanced startup page or whatever, then turned the computer on and kept pressing F8. Then a screen popped up asking me if I wanna boot from dvd, C: or E:. I just told it to boot from C and the screen went to "Resuming Windows" and started up fine.

Also it turns out that no, my windows aren't installed on the old drive. Because I ask it to boot from C: which is my new, main drive and it works fine. Can someone tell me what causes my computer to behave this way every time I try to boot from sleep mode (or potentially on any boot) even though it seems to be otherwise perfectly okay? I didn't make any changes to my computer that I know of that could have caused this. Is some piece of hardware failing and I don't know about it?

Hello omonoiatis9, would I be right in saying Windows is stored on the detected drive? Could you try going back into command prompt and entering 'sfc/ scannow' and see whether it finds any issues?

Hey, thanks for the reply. I am back today with more information that hopefully will help you help me.

I managed to get out of the startup loop. And the way was pretty weird. None of the command prompt commands I tried did anything, nor the startup repair itself did anything. I just clicked "shut down" from the advanced startup page or whatever, then turned the computer on and kept pressing F8. Then a screen popped up asking me if I wanna boot from dvd, C: or E:. I just told it to boot from C and the screen went to "Resuming Windows" and started up fine.

Now, here is what is also weird. This wasn't a one off issue. This now happens every single time I try to boot my computer back on from sleep mode (or potentially even from a full shut down, I didn't try it yet). Windows restarts and it goes into startup loop and the only way to get back in is the way I described. Also it turns out that no, my windows aren't installed on the old drive. Because I ask it to boot from C: which is my new, main drive and it works fine. Can someone tell me what causes my computer to behave this way every time I try to boot even though it seems to be otherwise perfectly okay? I didn't make any changes to my computer that I know of that could have caused this. Is some piece of hardware failing and I don't know about it?

Does startup repair give you an error at all? Are you able to boot into safe mode okay?

Startup repair finishes unable to find root problem. I didn't bother trying to boot into safe mode. My computer boots fine after I press F8 as it starts up and specify to it from which hard drive to boot. Which is strange, is it not? Did windows forget where it should boot from?

Also, let's assume that this is not a hardware problem. Would it be fixed if I upgraded to Windows 10 through microsoft's popup? I don't even shut down my computer now in fear that one day my current temporary solution will stop working.
