Restarting a computer fixes many problems. If the error continues to occur, do some further analysis to determine the underlying cause.
2. Disconnect all external devices like external hard drives, flash drives, and other USB devices, then restart the computer. again to see if that fixes it. These external devices can sometime interfere with the boot process some times. if this problem then remove them one at a time to figure out which one is the device is at fault.
3. Scan Windows for errors. If Windows loads successfully after a reboot, use the built-in Windows Error Checking tool also by command prompt using the chkdsk command.
4. The SFC scannow command which checks if correct System files are present  on the hard drive.
5. Boot into safe mode. When Windows doesn’t boot normally, you can often access the operating system in safe mode.
6. A system restore erases changes made to Windows since the selected rollback date, so back up files that you want to keep.
7. Disable Windows Secure Boot. The Secure Boot feature can prevent external hardware or software from working with a computer. Temporarily disable it to see if that fixes the problem.
8. Perform a system restore. If the problem started occurring after you installed a new device or program, use the Windows system restore function to roll back the operating system to a previous state.
9. Update the drivers. If you’re able to boot into Windows, check to see if all device drivers are up-to-date, particularly those related to I/O ports and storage.
10. Change the boot order. The boot sequence may have changed if you installed a new hard drive, plugged in an external drive, or connected a USB device. It can also occur when you update the system BIOS. Access the computer’s BIOS or UEFI settings, then make sure the hard drive that Windows is installed on is listed at the top of the boot sequence. Also update the volume boot code to use BOOTMGR. The volume boot code can become corrupted or associated with a boot loader other than the Windows default BOOTMGR. Updating the volume boot code should fix this problem.
11. Perform a Windows Startup Repair. If you can’t log in to Windows, use a Windows disc or a prepared USB drive that includes the Windows automatic repair tools. A Startup Repair can fix corrupt system files, registry errors, and missing content that sometimes cause this error to show up.

Download an antivirus program for Windows on another machine and copy it to a bootable drive. Most of the antivirus tools include a bootable rescue tool that scans a system from a command prompt.
13. Repair the Master Boot Record (MBR). Similar to the volume boot code above, the Master Boot Record contains data necessary for loading Windows. The MBR tells Windows which drive and partition to use during boot, so repairing the MBR might resolve the error.
14. Perform a clean install of Windows. Reinstalling Windows overwrites all changes made to the system. As a result, system files that were corrupted or missing are restored to proper working order.
15. Lastly, Check for component failures. We need look inside the computer for anything that may be loose or disconnected. Do the same for any external devices that caused the error.
