Here’s a step-by-step guide to help you fix common issues with the Windows Boot Manager:

Basic Troubleshooting Steps

• Reboot into Safe Mode: Before attempting any advanced fixes, restart your computer in Safe Mode. This will disable all non-essential startup programs and load only essential services.

• Check for malware: Run a full virus scan using an antivirus software to ensure no malicious software is causing the issue.

• Update Windows: Ensure that Windows is up-to-date with the latest security patches and updates.

Common Issues and Solutions

• Windows Boot Manager Not Showing: Check if the startup programs are properly set up in the registry. You can use the Registry Editor to modify the Windows boot settings:

* Press the Windows key + R, type regedit, and press Enter.

* Navigate to the following paths:

+ HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Windows\Startup

+ HKEY_LOCAL_MACHINE\SYSTEM\WindowsServices

* Check if the BootMGR is enabled in each location. If not, enable it and restart your computer.

• No Operating System Loading: Verify that you have enough disk space for Windows to install from a USB drive:

* Ensure you have at least 8 GB of available free space on the USB drive.

• Windows Not Detecting Disk: Check if the boot device is properly detected and not faulty:

* Boot into Safe Mode and press F2 during boot to access the Advanced Boot Options menu.

* Try booting with a different disk or check if the issue persists.

Advanced Troubleshooting Steps

• Disable Unnecessary Services: Disable any unnecessary services that might be conflicting with Windows boot loading:

* Open the Windows Registry Editor (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

* Look for any entries that are not essential for system functioning and delete them.

• Disable Boot Loader Services: Disable any services related to the boot loader itself:

* Open the Windows Registry Editor (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Boot

* Look for any entries that are not essential for boot loading and delete them.

• Update Boot Loader: Ensure that your boot loader is up-to-date with the latest versions:

* Open the Windows Registry Editor (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Boot

* Look for any entries related to the boot loader and update them.

Final Steps

• Reboot in Safe Mode: Once you’ve made necessary changes, reboot your computer in Safe Mode.

• Install Windows from a USB Drive: If none of the above steps resolve the issue, try installing Windows from a USB drive using a USB adapter or a different bootable media.

Prevention is Key

To avoid these issues in the future:

• Regularly back up important files to an external drive.
