Fix Windows 10 Won't Boot with Startup Repair and BootRec
User case: Windows 10 boot failure
How do you repair Windows 10 if it does not boot?
After a Windows 10 update, if it won't boot, try booting in safe mode, then run a System File Checker (SFC) scan and a DISM scan to identify and fix corrupted system files. If that fails, you can try a System Restore to a previous point before the update, or use a Windows installation media to repair the OS. If none of these work, consider reinstalling Windows 10.
- Question from HP Community
Windows 10 users often encounter the problem of their computer not booting successfully when turned on. This common issue can be caused by a variety of reasons, making it a frustrating experience for many users.
Why Windows 10 won’t boot?
To troubleshoot why your Windows 10 won't boot, it's essential to understand the Windows 10 boot process.
When Windows 10 starts, the BIOS or UEFI Firmware is loaded and performs a Power On Self Test (POST) on the hardware. The BIOS then scans the hard disk's master boot record (MBR), which loads the essential file WINLOAD.EXE into main memory.
WINLOAD.EXE initiates the start-up process by loading NTOSKRNL.EXE and HAL, after which Windows 10 begins to start up, performing tasks such as initializing hardware like the mouse and keyboard, and reading the Windows Registry and user profile.
Unfortunately, if there's an issue with WINLOAD.EXE, Windows 10 won't boot, and you'll encounter a black screen with the "Windows Boot Manager" title and an error message that reads:
File: \windows\system32\winload.exe
Status: 0xc0000605
Info: A component of the operating system has expired.
If you're experiencing a serious error with your Windows installation, don't panic. You can potentially fix the issue using Startup Repair or BootRec commands. These tools can help diagnose and resolve problems with your system's startup process, allowing you to boot into Windows normally again.
