Windows 10 machine stuck in Automatic Repair

Hello, I'm new here and I hope this is the correct place to post this.
I am not sure how to find the Windows version number on the PC that won't start. I have been doing my best to keep it up to date.
I came back from holiday yesterday, turned on our PCs.
My wife's PC is now stuck in a 'your PC did not start correctly' loop.
I have tried most of the options.
I even tried a system restore.
But nothing changes.
My PC is waiting to install updates but so far I have left it alone due to the issues on the other PC.
Thanking you in advance for any help,
Langston.

I am trying the system restore option again.

System restore didn't change anything

As samuria said maybe the CMOS battery is out. Since the computer was shut down for a while it may have lost critical startup information. And will loose them again if the battery is bad.

I would suggest "if you're not computer savy" to bring your computer to a technician that will replace your battery and re-configure your bios startup sequence.

or, if you're computer savy: Check battery... Reconfigure bios.

The battery is easy to see and change, look for a watch battery on your motherboard :)

What are the options which you tried?
Do you have a Windows Recovery drive and is your machine bootable from a USB drive ?

Thanks, guys. I'll see if I can replace the battery, otherwise I will take it to a repair shop.

I've replaced the battery. Still the same.

Changing the battery didn't change anything. Is there a simple to follow way to reconfigure the BIOS?

I can get into the BIOS but I can't figure out what to do there. I have tried obvious things such as 'load default settings' but with no effect.

The key things will be disk mode as that can stop boot it depends how it was setup. It could be uefi, legecy, secure boot or other if you don't know set one try if it doesn't work try another option. Are you booting ssd or HD as that gives a clue

Booting from HDD. There is an optical drive fitted to the PC.

Hi, as you say you tried System Restore, I'm guessing you forced it into the Advanced Startup options by pressing the power button to interrupt the boot loop 3 times.

Do you remember any message?
Was there a restore point available and did the restore complete?

If it did, that tells you the registry is probably ok, for example.

In this situation I would check the disk first (start from basics).
Two ways:
- create and boot from a live boot disk so you can check the SMART params using a program such as Crystal Diskinfo.
- from command prompt: see this tutorial
How to Check Drive Health and SMART Status in Windows 10

If ok, then try Method 6 here:

Another option: if you've been using Macrium Reflect for disk imaging as is so very often recommended here, then boot from its boot disk and use its useful 'Fix boot' utility.

The system restore was reported as successful but didn't take the PC out of the loop or change it in any obvious way.
I will probably be taking the PC to a local repair shop on Monday.
I really appreciate the help I am getting here. Nothing has been solved yet, but at least I have some idea of what is happening.
