If this error still exists, try to carefully unplug the main USB cables connected to the PC motherboard. This step will disconnect the troublesome USB device or follow another method from this guide.

Solution 3. Reboot the Power Cord

When the hard drive is not detected, it becomes impossible to access the boot manager. If your computer fails and doesn't recognize the hard drive, it may be due to improperly connected power and data cables. Consequently, this can lead to a "missing boot manager" error.

Follow the steps to fix it:

Step 1. Carefully open your computer case to access its internal components.

Step 2. Identify the hard drive and locate the power and data cables.

Step 3. Restart the system by disconnecting and then reconnecting these power and data cables. This action can resolve potential power or data connection issues.

Step 4. After adjusting the cables, turn on your computer and see if the issue is solved.

Note: Take these actions carefully because a little mistake can cause physical damage to your PC/laptop.

Solution 4. Change Boot Order in BIOS

Different computers may have differing BIOS configurations, but the process for modifying the boot sequence is generally consistent. Here are the steps:

Step 1. Access the BIOS menu during startup, typically by pressing the F2 or Delete key.

Step 2. Locate the "Boot" or "Boot Sequence" settings inside the BIOS.

Step 3. You'll find a list of bootable devices and their current order in these settings. Rearrange this sequence to match your desired method for Windows installation. For instance, if you're using a flash drive, set it as the primary boot device.

Step 4. Save the changes and restart your computer.

These steps will resolve the issue and give you access to the Boot Manager as needed.

Other problems related to the boot error:

Solution 5. Create a New Boot Sector

A "missing boot manager" error may be due to partition corruption or boot damage, particularly within the Windows partition. Several factors could contribute to these issues, including an old hard drive, virus infections, or malware attacks. To fix this, we suggest you create a new boot sector with the following steps:

Step 1. Start by accessing the start menu and searching for "Command Prompt."

Step 2. To enable developer configurations, right-click the Command Prompt option and select "Run as administrator."

Step 3. Type "bootrec /fixboot" into the Command Prompt and hit Enter to execute it.

Step 4. After running the command, a message will be shown: "Operation completed successfully."

Step 5. Now, restart your PC using the "Ctrl + Alt + Del" keys, and choose the restart option.

Note: Before restarting, all removable devices, such as USB drives or external hard drives, should be disconnected/unplugged from your system.

Solution 6. Rebuild Windows BCD

In the event of corruption or misconfiguration of your Boot Configuration Data (BCD), rebuilding it to resolve the "Windows boot manager is not showing in BIOS" error becomes necessary. The Boot Configuration Data is the crucial gateway to accessing the boot manager. Without it, access to the manager or even the visibility of its options is hidden.

Follow the steps:

Step 1. Search for "Change Advanced Startup Options" in the taskbar's search field. Click on it to open it after it shows in the search results.

Step 2. In the advanced startup option, click "Restart now". This action will redirect you to the advanced options menu.

Step 3. Choose "Troubleshoot," and then choose "Advanced Options."

Step 4. Choose "Command prompt" from the subsequent menu and wait for the Command Prompt to open.

Step 5. In the Command Prompt, type "bootrec/rebuildbcd" and press the "Enter" button. Wait a few moments. Once you see a successful installation message, you must adjust the attribute files in the next step.

Step 6. In the same Command Prompt, type "attrib c:\boot\bcd -h -r -s" and press Enter to remove the read-only and hidden files from the Windows bcd. Enter another command "ren c:\boot\bcd bcd.old," and it will rename the stored bcd. Now, you should have access to rebuild the BCD file.

Step 7. Type "bootrec /rebuildbcd" and press the Enter button. It asks you to add a boot to the list; here, you must type "Y" and hit Enter. Wait a few moments and let the "Operation successful" message appear on the screen.

Step 8. Finally, restart your PC/laptop to see the optimistic results and whether the issue is solved.

This solution is a litter complicated. You can try Qiling Disk Master for a quick and easy way. This solution also simplifies the process of rebuilding MBR.
