Windows Boot Manager does not appear in the BIOS boot list (but all the OS start via GRUB)

Question

Hi All,

My desktop computer with Windows 11 installed works perfectly, I have done various checks (Troubleshooting) also using the very useful PC Manager application and the response of all the checks done was positive "everything in order".

Hoping not to disturb I write here to clear up a doubt, it is about this: I am in multiboot with two NVMe disks (one reserved for Windows and the other reserved for Linux), installing the latest Linux distro (Endeavour OS, practically Arch Linux) I mistakenly left the default option for the boot loader (systemd), I should have chosen the "no boot loader" option because I already have native GRUB of the first distro installed (Linux Mint), the consequence is this: GRUB starts all operating systems regularly (including Windows) but if at startup I choose to access the BIOS I no longer find the "Windows Bootloader" item that was previously present and that I had placed as second boot option.

The question is: can I leave everything as it is and have no reason to worry or can or must something be done to make the "Windows Bootloader" item reappear in the BIOS?

To restore the Windows Bootloader this is the set of commands that I know, but I don't know if they are the right ones to use for this problem:

(Windows Power Shell)

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

Reboot

Thank you very much for your kind attention.

Kind regards

Silvio

Hello,

Thank you for posting in Microsoft Q&A.

Based on the description, I understand your question is related to Windows Boot Manager does not appear in the BIOS boot list.

You can consider boot in WinRE to restore windows bootloader, but it is necessary to backup your important data before the operation.

Insert a Windows 11 24H2 installation media (USB/DVD) and boot from it.

Select your language preferences and click Next.

Click Repair your computer.

Select Troubleshoot > Advanced options > Command Prompt.

Then run below commands:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

If the operation completes with no error, restart your computer and enter the BIOS setup. Check if the "Windows Bootloader" option has reappeared.

Have a nice day.

Best Regards,

Molly
