Windows won't start or repair

Hi,

This issue may occur due to a
missing/corrupted system files. We suggest that you perform these methods
of troubleshooting steps to fix this matter:

Method 1:
Run SFC Scan.

To run an
SFC scan, follow these steps:

• 
  Run
  Command Prompt as Administrator.
  
• 
  Type
  sfc /scannow
  and hit
  Enter.
  

This will check and run an auto-repair on the issue.

Method 2:
Run DISM Tool.

After running the
SFC scan
and the issue still persist, run the
DISM
to check the system health and to try restoring the files. To run
DISM tool, follow these steps:

• 
  Run
  Command Prompt as Administrator.
  
• 
  Type the following command:
  
  • 
    DISM.exe /Online /Cleanup-image /scanhealth
    
  • 
    DISM.exe /Online /Cleanup-image /Restorehealth
    

NOTE:
This might take a while to finish scanning.
Do not cancel.

Let us know how it goes.

Regards.

Scanning and repairing drive on every start-up

Recently, I had a start-up error with the "Reboot and select proper Boot device" message. I fixed it by unplugging and then plugging back in my drives, but since then it has been slow with starting up Windows, attempting to scan and repair an unknown drive before the login screen.

I need help to figure out which disk it is referring to and how to get rid of the scan and repair thing on start-up.

Windows Version Number: 1903 (OS Build 18362.900)

(Link to the previous thread: Scanning and repairing drive on every start-up
Tried the things listed there, but couldn't get much further. Was suggested to start this new thread...)
