-## Chain NixOS in same disk with other systems
-
-To install NixOS on a partition along another system which controls the GRUB,
-first disable the grub device, so the GRUB is not installed in the disk by
-NixOS (only the /boot files will be generated):
-
-```
-boot.loader.grub.device = "nodev";
-```
-
-Then add the following entry to the old GRUB configuration:
-
-```
-menuentry 'NixOS' {
-        insmod chain
-        search --no-floppy --label nixos --set root
-        configfile /boot/grub/grub.cfg
-}
-```
-
-The partition with NixOS must have the label "nixos" for it to be found. New
-system configuration entries will be stored in the GRUB configuration managed
-by NixOS, so there is no need to change the old GRUB settings.
