Windows 10: No login prompt and cannot boot in safe mode.

Am helping a friend set her PC back up after it has been stored (everything unplugged) for about 9 months.
When we first went to turn it on the fans kicked in and it would appear to start booting up but then turn itself off again after about 10 or so seconds of activity.
It did this 3 times and on the 4th attempt it finally loaded.
However, it loaded as far as the login screen and when we mouse click or press a button the time etc clears from the screen but the login prompt is not there at all.

Have searched through forums and seen mention of similar problems solved by booting in safe mode.

I cannot get this PC to boot in safe mode.

Shift+Restart - the pc says it is restarting but just shuts down.

Power on and interrupt loading 3 times to try and get Automatic Repair Mode to trigger has done nothing. It will just load to the login screen again once I let it load fully.

I even tried holding F2 while turning it on to try and get to BIOS, but this did nothing.

I'm stumped at this point, how can I get this PC to boot in safe mode?

command prompt will not open in safe mode with command prompt

I am repairing a laptop for a friend and I need to access windows in safe mode and the owner has forgotten the password to the main user. I tried logging on with the administrator profile in safe mode but it is not showing up so I was going to use command prompt in safe mode with command prompt but command prompt will not open when I boot that option. Does anyone have any hints for me to figure this out?

Would I just follow the same steps within safe mode after hooking up to the other system?

Hi,

Thank you for posting your query on Microsoft Community forum.

Have you tried all the above steps suggested by Sangeeta Sarkar on September 13, 2015.

I would suggest you to provide some information to help you better.

• Are you trying to login the Microsoft account or the Local account in safe mode?
• Did you try with only safe mode or safe mode with networking?
• What is the critical error you are getting?

If you are using Windows 10. To go to safe mode you have to follow the below steps.

If you are able to go to login screen in normal mode try the below steps to go to safe mode with networking.

• 
  At the login screen click on the power symbol.
  
• 
  Hold SHIFT + Click Restart.
  
• 
  After restarting your system, select the Troubleshoot option.
  
• 
  Select advanced options under
  Troubleshoot screen.
  
• 
  Click on Startup Settings.
  
• 
  Click Restart and follow the onscreen steps to go to
  Safe Mode with networking and check if you are able to login.
