I understand it goes to automatic repair.     click on advanced options 


On the advanced options,  go to startup settings - click on restart -  It will show you the list of options.  chose 5 to go to safe mode with networking..    Please check whether you are able to start the computer in safe mode with networking .   You can always chose no 5 or f5 on keyboard to go to safe mode with networking on the list of options.   It will show you the login screen.    Type the password and  it will show you all the icons.   Now you are in safe mode with networking.. 

Try windows x - click on shutdown  - restart.   It will start the computer to regular mode now.    

If you are not able to see the startup settings on advanced options then please try system restore..

On the advanced options , click on system restore,  chose a date you would like to restore and restore your computer to an earlier date on which it was working fine.. 

If both the options are not working, click on troubleshoot, click on reset this pc 

It will show you keep my files and remove everything

chose keep my files 

chose the account - type the password - click on local reinstall - click on reset 

It will be in progress.. 

login to computer and start using the computer. 

If it is still not working try the step 2  

Step 2 

chose remove everything 

click on local reinstall - just remove my files - click on reset  - It will be in progress

If you do refresh ( keep my files ) -  all your personal files like pictures, music , documents , videos  will still be intact.   Only the applications will be lost 

If you do reset  ( remove everything )  - you are doing a factory default.   It will become like a day one computer.    It will wipe out everything and take your computer to day one like a new computer. 

If it is still not working you have to follow these steps in a different way. There are two alt keys on the keyboard.  If you look at the bottom row of keyboard you can see the one on the left side of space bar and the other on the right side of space bar.  The alt key on the right side will be looking like alt, alt gr or alt car.  Turn off the computer.  Hold the alt key on the left and tap f10 continuously.   It will go to repair mode.  It will show you – use device, continue , troubleshoot.  If it is not going to repair mode, turn off the computer.  Turn on the computer.  Hold the right alt key ( alt gr or alt car or alt )  and then tap f10 continuously.  It will go to repair mode.  It will show you – use device, continue , troubleshoot.   Click on troubleshoot – reset this pc –  It will show you keep my files and remove everything 

You can try the keep my files..   It will refresh your computer
