User case: Windows 10 boot failure
How do you repair Windows 10 if it does not boot?
Hello, guys! I have a HP computer installed with Windows 10 operating system. It works fine until a recent update - the Windows 10 won’t boot after recent update. I’ve tried to repair the program, but the Windows 10 boot failed again. Is there a way to fix Windows 10 won’t boot without reinstalling?
- Question from HP Community
Actually, there are many users who have met the problem that Windows 10 won’t boot successfully when they turn on the computer. Well, “Windows 10 won’t boot” is a common issue that can be caused by many reasons.
Why Windows 10 won’t boot?
To figure out why your Windows 10 won’t boot, you need to know about the Windows 10 boot process:
When Windows 10 starts, the BIOS or UEFI Firmware is loaded and performs a small set of checks on your hardware called Power On Self Test (POST). And then, the BIOS scans the hard disk master boot record (MBR), which loads an essential file into main memory called WINLOAD.EXE.
WINLOAD.EXE kicks off the start-up progress by loading the NTOSKRNL.EXE and HAL. Then, Windows 10 starts up and performs tasks such as initializing hardware like mouse and keyboard and reading the Windows Registry and user profile.
However, if there is anything wrong with WINLOAD.EXE, the Windows 10 won’t boot and you will see a black screen titled “Windows Boot Manager” with an error reads:
Info: A component of the operating system has expired.
This could be a serious error, but don’t panic. You can fix the error with Startup Repair or BootRec commands.
How to use Startup Repair or BootRec commands to fix Windows 10 won’t boot
A black screen and Windows 10 boot failure often mean that your master boot record is on the fritz. And here, you can try to fix the issue with Startup Repair and BootRec commands.

Booting into Windows recovery environment (Windows RE) to perform a Startup Repair can easily fix problems that keep Windows from loading. You can follow the steps below:
1. To access Windows RE, you need to turn your computer on and off three times. Make sure you turn off the computer when you see the Windows logo. After the third time, Windows 10 will boot into diagnostics mode. Click Advanced options when the recovery screen appears.
2. Then, click Troubleshoot to get into the screen of Reset your PC or Advanced options.

- BOOTREC /FIXMBR (this command will fix any corruption issues with the master boot record)
- BOOTREC /FIXBOOT (this command will attempt to write a new boot sector on the hard disk if Windows detects damage)
