[FIX] Windows fails to load in PC

Many times we have a PC running smoothly but suddenly something bad happens like Power goes off and the system files fails to load afterward and Windows gets corrupted. When you again try to use the computer either of the two things happens:
  1. A continuous loop of Boot Screen of Windows.
  2. You get a message that Windows did not start correctly.

CASE-1 You cannot get to the desktop.

Many times due to faulty drivers/updates/programs your PC might hang on boot screen, or you get a blank screen. In any of such cases where you cannot go to the desktop, you need to directly restart your PC three times(or do a direct shutdown 3 times)using the Reset button. This makes your PC go into recovery mode. Now you can use diagnostics in case 2 given to correct your issue.

Case #2 provides you some options to diagnose your PC by going to advanced options, which we would discuss here in this article.

CASE 2- Windows did not start correctly

In this case, first of all a restart can help, as written in the image, but there are fairly fewer chances. If that doesn't help, proceed to next options available.

Method 1: Run a startup repair

  • Click on troubleshoot on the right and it should open up plenty of options. You need to select Automatic repair and then Proceed.
  • The system would reboot and then your PC would be diagnosed.
  • Enter your Username and Password if prompted. Click on next.
  • If it is successful, Windows would automatically reboot to desktop. If it doesn't we need to try other options. You would be told though, if it was successful.

Method 2- Running a Disk check 

Sometimes disk corruption can also lead to corruption of the OS System files. You can then proceed to disk check and see if that helps. Steps are the following:
  • Navigate to the troubleshooting section and Select Command Prompt on right.
  • Enter your username and password if prompted. This opens a new Admin Command Prompt Window. Enter the following command to run the disk check:
  • chkdsk /r
  • It might take hours to finish, depending on the level of corruption.
  • If it is successful, your system would boot to the desktop on next reboot. 

Method 3- If the PC shows BCD/MBR is corrupt

  • If method 2 and 1 did not help and the PC says you need to fix BCD/ MBR as shown here, then this step is exclusively for you. Other users can also try this in case, it fixes the things. Master boot record and Boot configuration file stores the data about the OS location.
  • Navigate to the same troubleshoot Section and select Command Prompt- Present on the right. It opens a new command Prompt Window.
  • Now enter the following commands one by one to fix the Master boot record:
Restart and you should be good to go. If it doesn't help. You can try repeating the same steps by entering the following command instead of the above 4:
 bcdboot C:/Windows
Substitute C: with the drive where Windows is installed.

Method 4: System Image recovery

If you regularly do backups and have a system Image saved on your hard drive, then this might come handy to you.  A system Image is an exact copy of the OS running on your system. The downsides are-It would restore your files and settings to what it was when the Image was created, but a beautiful method if you want your PC up and Running.
  • On the same troubleshooting section, click on System Image recovery.
  • Now Windows would scan your PC for target operating system. Select the respective Windows

  • Windows would then restore your system Image.

Method 5- Resetting your PC

This is the last resort. With a reset, all of your Installed applications are lost, but you get an option to save your files if you want. If a system image from the OEM exists-called a recovery partition, then it also gives you an option to restore it. It would make your PC load to default factory settings.
  • Navigate to Troubleshooting section, again.
  • Select Reset. Now you are prompted with 2 or 3 options as here:
  • If you select keep my files, your files would be kept. You might also get the third option-restore to factory settings-which isn't applicable on the PC.
  • If you select remove my files as well, you are asked the following:
  • After selecting the desired options, you are presented with a confirmation, something like this- This indicates what you have chosen. 
  • Click on Reset and the resetting should begin.

Method 7- Clean Install

A Clean Install is the best method when nothing helps. Just boot from a Windows 10 media and run the setup. Format the drive for best results and you are good to go! The following article by Greg Camarack explains this in detail:

That's it. Please give feedback if any.
