Zorluk: KolayTroubleshooting Windows OS Startup and Boot Errors

A computer running Windows fails to start due to a corrupted Boot Configuration Data (BCD) file. Arrange the following repair steps in the correct sequential order from first to last.

  1. 1Boot the system using Windows installation USB media and select Repair your computer.
  2. 2Navigate to Troubleshoot > Advanced options and launch the Command Prompt.
  3. 3Execute the bootrec /scanos command.
  4. 4Execute the bootrec /rebuildbcd command.

Cevap

The correct troubleshooting sequence is: 1) Boot using Windows installation USB media and select Repair your computer, 2) Navigate to Troubleshoot > Advanced options and launch the Command Prompt, 3) Execute the bootrec /scanos command, and 4) Execute the bootrec /rebuildbcd command.
The recovery sequence must begin by loading Windows Recovery Environment (WinRE) from external installation media because the corrupted BCD prevents normal booting. Opening the Command Prompt from Advanced options allows access to repair utilities. Running 'bootrec /scanos' scans connected drives to detect valid operating systems. Finally, running 'bootrec /rebuildbcd' rebuilds the BCD store and adds the detected installation back to the boot menu.

Adım Adım Çözüm

1
Insert Windows installation media and boot the system into the Windows Recovery Environment (WinRE).
Access to external system repair menus is achieved.
A corrupt BCD prevents normal local booting, requiring repair tools to load from media.
2
Select Troubleshoot, open Advanced options, and click Command Prompt.
An elevated command-line window opens in the recovery environment.
Bootrec commands require a command-line prompt within WinRE.
3
Run bootrec /scanos to locate Windows installations.
All connected storage drives are scanned for active Windows installations.
Verifying existing installations ensures the utility detects the OS before updating BCD references.
4
Run bootrec /rebuildbcd to recreate the BCD store.
The Boot Configuration Data file is reconstructed with valid boot entries.
This step writes the new boot configuration entries so Windows can locate the operating system loader upon startup.
