How can I add Windows 11 to grub menu?
My issues started when I partitioned my Ubuntu 22.04 LTS drive to add Windows 11 (I used my Ubuntu bootable to partition the drive). Once Windows 11 was installed, my computer began to boot Windows 11 instead of showing me the grub menu. I fixed this by entering the BIOS and moving Ubuntu to the top. My computer was booting into Ubuntu now, but I still wasn’t seeing the grub menu. After looking at this post, Why is Grub menu not shown when starting my computer?, I was able to get my grub menu to show again (@Akalgnotum). But Windows 11 was not included in the menu. With the guidance of this post, GRUB does not detect Windows I ran: sudo os-prober which returned /dev/nvme0n1p1@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi . I then ran sudo update-grub which gave me this «warning»:
Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file . Found linux image: /boot/vmlinuz-5.15.0-46-generic Found initrd image: /boot/initrd.img-5.15.0-46-generic Found linux image: /boot/vmlinuz-5.15.0-43-generic Found initrd image: /boot/initrd.img-5.15.0-43-generic Memtest86+ needs a 16-bit boot, that is not available on EFI, exiting Warning: os-prober will not be executed to detect other bootable partitions. Systems on them will not be added to the GRUB boot configuration. Check GRUB_DISABLE_OS_PROBER documentation entry. Adding boot menu entry for UEFI Firmware Settings . done From what I gather, Windows won’t be added by sudo update-grub because it won’t run and use the information given by os-prober. I have no idea how to fix this. Any suggestions would be extremely helpful. If more information is needed, I’ll be happy to provide it. Thanks!

How to add Windows to GRUB
I have my encrypted Archlinux installed on my SSD. Now I have one HDD with Windows installed. But in my GRUB just Archlinux is shown (no Wonder, because I just installed Windows on the other HDD, GRUB doesn’t know of that by now.). My Question is, how do I properly add my Windows-HDD to GRUB, so that I can choose which to boot when starting? I am a little bit afraid of destroying my GRUB so I can’t boot my encrypted Archlinux anymore. Thanks!
Look at your grub config file grub.cfg and add a menu entry to chain load windows. Search terms: ‘chain boot’ ‘grub.cfg’

Save a backup of your all your grub configuration files.
There are two methods I have used in the past:
1) Install ntfs-3g (which should allow your installation to see the windows partition automatically) using your package manager. It was available in the EPEL repo for me, but you’ll have to find a different repo for it on Arch.
Then sudo grub2-mkconfig . This worked for me while trying to get my centos7 dual boot to work with windows.
2) Alternately, you’d be best off adding a custom entry by adding a file to /etc/grub.d/
For example, on my current system which is a Centos7 + Windows 10 dual boot:
$ sudo cat /etc/grub.d/40_custom #!/bin/sh exec tail -n +3 $0 # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. menuentry "Windows 10"
Where the menuentry parameter is the name that will appear in the grub menu. The (hd0,1) will change depending on what hard disk and what partition you have windows on.
Как добавить windows 10 в меню загрузки grub?
На ssd стояла windows 10.
Разбил hdd под установку linux mint, но после его установки загружалась только windows 10. Решил это чистой установкой Linux, установщик разбил диск как ему надо. Как итог linux грузится, windows 10 — нет, и кроме того не могу войти в настройки bios: меню загрузки там пустое, bios setup не открывается.
В меню загрузки grub есть только linux.
Есть ли способ добавить windows в меню загрузчика grub, как убедиться, что она сможет запуститься, и это не убьет работающий Linux?
Grub выглядит так:
По команде lsblk результат такой:

Добавил руками пункт загрузки в grub как написано в статье.
При выборе — error: invalid EFI file path.
ps. Если бы была возможность зайти в bios, с удовольствием бы снес все и накатил заново винду (или восстановил с загрузочной флешки). С проблемой столкнулся не впервые, но в прошлый раз пришлось прибегнуть к прошивке bios на программаторе. Хотелось бы обойтись без такой хирургии, тк не желательно отдавать ноут на несколько дней.
