The Windows 10 boot process is really simple. Whenever your computer starts, the BIOS or UEFI Firmware is loaded actually, which performs a small set of checks on your hardware that we called the Power On Self Test (POST). The BIOS then scans the hard disk master boot record, which loads an important file into the main memory called WINLOAD.EXE. This basically kicks off the start-up process through loading the NTOSKRNL.EXE (NT Kernel, the heart of Windows) and HAL (Hardware Abstraction Layer.). The Windows 10 then performs tasks like initializing your hardware such as your mouse and keyboard and reading the Windows Registry and user profile as well.

If you guys see a black screen along with gray text that reads “Windows Boot Manager” along with an error along the lines of “Status: 0xc0000605 Info. A component of the operating system has expired as well,” then it means something went wrong along with WINLOAD.EXE actually.

If you guys are unable to perform a startup repair, then your next option is to try using your Windows 10 installation media in order to fix the boot error.

If you do not have installation media, then you will need to go to a working computer and then Create a Windows 10 USB Bootable Flash Drive. You can also head to a working Windows 10 PC and then create a recovery drive as well. When you use a USB drive, then make sure to set up your BIOS in order to boot from the USB drive.

After you boot into setup, then select the Repair Computer option > Troubleshoot > Advanced Options > Command Prompt. If you are using a recovery drive, then you have to tap on Troubleshoot > Advanced Options > Command Prompt.

When you have the command prompt up on the screen, then you will need to issue a set of commands. In order to find and resolve issues that might be avoiding your computer from booting as well.

This command will then attempt in order to write a new boot sector on the hard disk if Windows detects damage. Mostly, this happens in cases where an older version of Windows was installed, or a non-compatible operating system for example Linux was installed.

If you guys are seeing an error like Boot Manager is Missing, then the bootrec  or RebuildBcd command might be able to fix it actually. This operation can also restore boot entries for older versions of Windows if you guys have a dual boot configuration actually.

If bootrec  or RebuildBcd does not work, then Microsoft recommends you to back up your BCD (Boot Configuration Data) save. Then run the bootrec /RebuildBcd command again as well. Here is how you can do it.

  • cd boot
  • attrib bcd -s -h -r
  • ren c:\boot\bcd bcd.old
  • bootrec /RebuildBcd

Another option if you are dual booting along with older versions of Windows like Windows 7 is the BOOTREC /ScanOs command. The ScanOS command can find and restore the entries for older versions of Windows as well.

Change BIOS Settings

You have to choose the boot mode according to the type of disk on your system actually. If you guys want to start an MBR system disk, then you can choose Legacy support rather than UEFI in boot mode. In order to start a GPT system disk, then you need to choose UEFI.

How can you access BIOS: Common keys in order to enter the BIOS are F1, F2, F10, Delete, Esc, as well as key combinations such as Ctrl + Alt + Esc or Ctrl + Alt + Delete.
