Hi Anik, I am Rob, a volunteer and a 10 time and dual award MVP specializing in Windows troubleshooting and Bluescreen analysis. Please remember as volunteers we are not responsible for the development of Windows or the computer hardware and drivers.

This is a very serious error, often hardware.

You will need a Windows 10 boot disk if you don't have one (see below).

Boot with a Installation or Repair disc or USB drive - issue these from the Command

Prompt and hit ENTER after each.

C:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

After the above you may need to run Automatic Repair (even 2 or 3 times) - Option 5 here and run StartUp Repair to see if it helps.

Using EasyBCD often works when other methods do not. <-- if Bootrec did not help use this.

Answer 3

Power on and off your computer three times

On the third time, your computer will boot into the Advanced Recovery environment

Click Advanced Options

Click Troubleshoot

Click Advanced Options

Click System Restore, see if you can go back to an earlier time.

If not, boot into the recovery environment again, then try performing a startup repair.

If that does not work, boot into the recovery environment, then click 'Go back to previous version of Windows'

If that does not work.

Go to a working computer, download, create a bootable copy, then perform a clean install.

Answer 4

Hi Anik. I'm Greg, a volunteer installation specialist and 8 year Windows MVP, here to help you.

1. Use whichever method works in this link to access Advanced Startup Options: https://www.tenforums.com/tutorials/2294-advanc.... Easiest may be to restart PC three times to trigger the Startup Options.
2. If none of the other methods work it may be necessary to Create Windows 10 Installation Media on another PC: http://windows.microsoft.com/en-us/windows-10/m...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...

Choose the boot device as a UEFI device if offered, then on second screen choose Repair Your Computer. If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

3. In the Advanced Troubleshooting options try to System Restore to a point before the problems began, Startup Repair, then if necessary from Startup Settings try to get into Safe Mode with Networking, or lastly Safe Mode.

If Startup Settings aren't available you can force Safe Mode from Command Prompt using the command to unhide F8 Advanced Startup Options here: https://www.digitalcitizen.life/4-ways-boot-saf.... Try Last Known Good Configuration and then Safe Mode with Networking.

4. From Safe Mode w/Networking work through the Windows 10 Install Integrity Checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get donehttp://answers.microsoft.com/en-us/windows/wiki/windows_10-performance/windows-10-performance-and-install-integrity/75529fd4-fac7-4653-893a-dd8cd4b4db00: If it doesn’t fix Windows enough to start it normally, then try a Windows 10 Refresh: https://www.howtogeek.com/265054/how-to-easily-...
5. If Safe Mode doesn’t work or help stabilize things then return to Advanced Troubleshoot options. Next try Command Prompt to run through Windows 10 Install Integrity Checklist (above link) repair commands including sfc /scannow, DISM, a full Disk Check, or return to Troubleshoot options to Reset Your Windows 10 PC.
6. Better yet do the vastly superior Clean Install Windows 10 following the steps in this link to delete all partitions down to Unallocated Space to get it cleanest: http://answers.microsoft.com/en-us/windows/wiki...
7. There is a step to Rescue Files from the booted media Command Prompt first: http://answers.microsoft.com/en-us/windows/wiki...
