It seems i need to do this:
If you want to dual-boot with Windows (this is unsupported)! :warning:
Make sure you install Windows first. This is technically optional if you have a UEFI system and know your way around changing the default bootloader, but installing Windows first is the easier way.
Make sure to select “install alongside” in the partitioning step in the installer.
If you install M$ as second OS, you must later repair the grub part with the live ISO via chroot.
Just search in the forum, it’s explained often.
Using on one drive is possible, repair just grub.

If something goes wrong, and you can’t help your self,
we wrote before, dual-boot with Windows is unsupported :warning:
((Dual Booting Windows 11 with Garuda Linux - #3 by SGS))
So if i understand correctly, i create a partition for windows, but what do i do then?
By the way i should still have windows 11 from before i switched to Linux and i still see ‘windows’ in the boot menu sequence.
And after i manage to install windows, do i follow this to fix the GRUB?
