Our computer is a work medium for many of us, so it is important to make good use of it. Starting Windows 10 is the first step we must take to access the system and with it all the programs, applications and functions that we constantly carry out there.. 
     
    
  As users, it is enough to press the power button on the PC and that's it, but internally a series of physical and logical processes come into play so that the system loads as it should in terms of services, environments and user profiles so that that if any of this fails we will be in trouble since we will not have access to the login. 
     
  There are various causes of this error and in TechnoWikis we will explain how to correct it to have a full and complete login in Windows 10.. 
    
    
  Fix error computer boots but does not start Windows 10 
     
  Step 1 
  When boot failures occur, we can try to restart the PC 3 times to access the integrated Automatic Repair function: 
   
  
 
    
  Step 2 
  When presenting a boot error automatically Windows 10 will start the automatic repair diagnosing the PC: 
   
  
 
    
  Step 3 
  Then it is possible to see the following message. We click on "Advanced options" to see the following: 
   
  
 
    
  Step 4 
  We click on "Troubleshoot" to access other options: 
   
  
 
    
  step 5 
  We click on "Advanced options" 
   
  
 
    
  step 6 
  We will have access to the set of options: 
   
  
 
    
  step 7 
  First of all we click on "System Restore", this function, if it is enabled, will give us the possibility of returning the PC to a previous date where everything worked correctly, when clicking there we must select the user: 
   
  
 
    
  step 8 
  Then enter the password: 
   
  
 
    
  step 9 
  Confirm if there are restore points to return the system to one of them: 
   
  
 
    
  If this is not the case, we click Cancel but if there are restore points, it will be necessary to select it and confirm the restoration process. 
    
  step 10 
  We will see again the following: 
   
  
 
    
  step 11 
  We click on "Troubleshoot" and then on "Advanced options": 
   
  
 
    
  step 12 
  Then in the general options we click on "Startup Repair": 
   
  
 
    
  step 13 
  This is one of the functions integrated into Windows 10 that is responsible for analyzing the disk to detect and correct factors that affect the system boot, clicking there will start the analysis: 
   
  
 
    
  step 14 
  Wait for the process to run: 
   
  
 
    
  step 15 
  After this, an attempt will be made to apply the corrections so that the system loads as expected: 
   
  
 
    
  step 16 
  We hope it works, if it doesn't, in case it is not possible we will "Solve problems": 
   
  
 
    
  step 17 
  Then we click on "Advanced options": 
   
  
 
    
  step 18 
  Then we click on "Command Prompt": 
   
  
 
    
  step 19 
  We select the user and enter the password to access the terminal, there we access drive C:  
 c:     
  
 
    
  step 20 
  List the content: 
 say 
  
 
    
  step 21 
  In case of error we have to look for the letter assigned by the system and then list its content with "dir": 
   
  
 
    
  Note: to know the letter where Windows 10 is installed, run "diskpart" and then list the volumes with the "list vol" command, the letter where the largest disk is is where Windows 10 is installed.. 
    
  step 22 
  We access the directory: 
 cd \Windows\System32\config 
  
 
    
  Step 23 
  We create a backup: 
 md backup 
  
 
    
  step 24 
  We copy the elements: 
 copy *.* backup 
  
 
    
  step 25 
  Access the copy of records: 
 cd RegBack 
  
 
    
  Step 26 
  We list the content: 
 say 
  
 
    
  Step 27 
  Try to copy (if they exist) the elements: 
 copy *.* .. 
  
 
    
  Step 28 
  We left the console to see the following: 
   
  
 
    
  Step 29 
  We click "Continue" to log in to Windows 10: 
   
  
 
    
  step 30 
  We start the session: 
   
  
 
    
  step 31 
  we will have normal access to Windows 10: 
   
  
 
    
  With these steps it will be possible to recover access to Windows 10 without any problem.
