OS
Windows 11
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 am writing 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 GRUB native to 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 the 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" entry 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

as long as you have GRUB installed GRUB will act as the boot loader for all systems that GRUB has registered within the boot loader.
the only time you would need to reinstall the Win Boot Loader would be if you decided to remove all the Linux operating systems from your computer upto and including GRUB which can be used as a standalone boot loader for the system if required.

this should give you an insight to how GRUB works for both Windows and Linux or/and dual boot.

Hi Freebooter, thanks :) I subscribed to your YouTube channel, but I would like to make a suggestion: interesting tutorials like this one, in my opinion, would be more practical/convenient to propose them in written form, not video.
