To fix Windows installation errors using the BIOS (Basic Input/Output System) recovery, you’ll need to:

• Boot into BIOS: Restart your computer and press the key that was used for the initial boot-up process to enter the BIOS setup. For most systems, this key is F2 or Del.

• Save changes and exit: Save any changes made to the BIOS settings and exit the BIOS setup.

Common Windows Installation Errors:

• “Windows cannot find C:\\Windows”

• “Windows cannot find C:\\Windows\\System32”

• “Windows cannot find C:\\Windows\\System32\\cmd.exe”

• “Installing Windows was cancelled”

BIOS Recovery Steps:

1. Disable Fast Startup and Disable Hibernation

To prevent corrupted system files, disable Fast Startup and Hibernate during the installation process.

Method 1: Using the BIOS Setup Menu

• Press F2 to access the BIOS setup menu.

• In the Advanced Boot Options menu, navigate to Secure Boot > Disable Fast Startup (or Hibernate).

• Save changes and exit the BIOS setup.

2. Reinstall Windows from a USB Drive or CD/DVD

If you can’t boot into your computer’s main operating system, try reinstalling Windows from a USB drive or CD/DVD.

Method 1: Using Windows Media Creation Tool (for Windows 10/11)

• Insert the installation media.

• Go to Settings > Update & Security > Recovery.

• Click on Get started with installing Windows.

• Follow the prompts to reinstall Windows.

3. Rebuild a System Image

If you’ve already installed Windows and it’s not recognized by your computer, try rebuilding a system image using System File Checker (SFC).

Method 1: Using Command Prompt

• Restart your computer and enter Safe Mode.

• Open Command Prompt as an administrator.

• Run the following command:

sfc /scannow

4. Repair Windows Installation

To repair the installation, follow these steps:

Method 1: Using System File Checker (SFC)

• Restart your computer and enter Safe Mode.

• Open Command Prompt as an administrator.

• Run the following command:

sfc /scannow

If you’ve already run SFC, try running System Restore to revert back to a previous version of Windows.

Method 2: Using Disk Check

• Restart your computer and enter Safe Mode.

• Open Command Prompt as an administrator.

• Run the following command:

chkdsk C:\Windows

If you’ve already run chkdsk, try running System Restore to revert back to a previous version of Windows.

5. Reinstall Windows from a Professional Copy

If none of the above steps work, try reinstalling Windows from a professional copy (such as a Microsoft Volume Licensing Service Center).

Method 1: Using System Image Recovery Tool

• Restart your computer and enter Safe Mode.

• Open Command Prompt as an administrator.

• Run the following command:

mbrutil C:\Windows

If you’ve already run mbrutil, try running System Restore to revert back to a previous version of Windows.

Additional Tips:

• Make sure your antivirus software is enabled and up-to-date.

• If you’re using a virtual machine, shut it down before attempting to fix the installation error.

• Be patient during the troubleshooting process, as fixing BIOS-related errors can be time-consuming.

By following these steps, you should be able to identify and resolve Windows installation errors using the BIOS recovery.
