How to Remove or Work with Windows Boot Manager in BIOS

Windows Boot Manager (WBM) is an essential component that allows your system to boot into Windows. Occasionally, you may need to modify or remove it for various reasons, such as dual-booting systems or fixing boot issues. This guide will walk you through the steps to remove or adjust Windows Boot Manager in the BIOS/UEFI settings.

Why Modify or Remove Windows Boot Manager?

If you have multiple operating systems (OS) installed on your computer, you might want to ensure that the boot manager is correctly configured to avoid errors or unwanted system prompts. Alternatively, if Windows Boot Manager is causing your system to fail to boot, you can attempt to remove it to resolve the issue.

Steps to Remove Windows Boot Manager from BIOS

Access the BIOS/UEFI Firmware Settings

1. Restart your laptop: You need to access the BIOS/UEFI settings before the operating system boots up.

2. Press the appropriate key: Once you restart, press the key that opens the BIOS/UEFI settings. This key varies depending on your laptop model. Common keys include:

Function (F) keys: F2, F10, F12 Esc Delete

Refer to your laptop’s manual to find the correct key for your model.

Navigate to the Boot Menu

1. Once you access the BIOS/UEFI firmware settings, use the arrow keys to navigate to the Boot menu or tab. The exact name and location can vary depending on your BIOS version.

Locate and Modify Boot Options

1. Locate boot options: Search for a list of boot options or boot order. This list should display your current boot device configurations.

2. Remove or disable Windows Boot Manager:

Depending on your BIOS version, you may have the following options: Disable: Highlight the Windows Boot Manager option in the list, and select the option to disable it. Delete: If there is an option to delete, select it. Change Boot Order: If you prefer not to have it as the first boot option, you can move another boot device like your hard drive to the top of the list.

Save Changes and Exit BIOS

1. Save changes: After making the necessary changes, navigate to the Exit menu and choose the option to Save Changes and Exit.

2. Confirm prompts: Follow any on-screen prompts to finalize the changes.

Additional Considerations

Check for Boot Issues

1. Repair Startup Issues: If your laptop was previously stable without these changes and now encounters problems, consider performing a startup repair or checking for corrupted system files using a Windows installation media.

Backup Important Data

1. Before making significant changes: It’s always a good idea to back up your important data. This can prevent data loss in case of any unexpected issues.

If the Issue Persists

If the issue continues, or you are unsure about making these changes, consider consulting a professional or reaching out to the laptop manufacturer’s support for assistance.

It is worth noting that if you wish to continue using Windows, do not delete the Windows Boot Manager, as it is essential for booting the operating system.

If you need to repair it, consider either reinstalling Windows or using system integrity maintenance (DISM) options. For example, you can use the following commands:

sfc /scannow

Alternatively, you can explore DISM options for further repairs.

Your computer will not boot into the OS without the Boot Manager. If you have multiple OS installed, this manager allows you to choose which OS to load at boot. In some cases, you might need to reload Windows after formatting your hard drive.
