I found the file where the menu is listed, but it says you should not edit it, and instead points me to another file in which I have no idea what to do

put something like this in 40_custom
Code:
#!/bin/sh -e
echo "Adding Arch Linux to GRUB 2"
cat << EOF
menuentry "Arch Linux" {
set root=(hd0,4)
linux /boot/vmlinuz
initrd /boot/initrd
}
EOF
echo "Adding Arch Linux to GRUB 2" just displays during update-grub. change it to what ever you want
menuentry "Arch Linux" is what will show in the grub menu
set root=(hd0,4) means device 1 partition 4
It's a little different in grub2 device numbers start at 0 and partitions start at 1
I believe you said sda4 is your arch install so that would be hd,0,4
And of course adjust /boot/vmlinuz and /boot/initrd to what ever is in your arch boot directory
Make the script executable
And last but not least run update-grub as root
Also if you change the number in 40_custom to a lower number it will appear higher in the boot order .
So if debian is 20 make this 15 and it will be before debian. You can even change the rest of the name to
anything you want
just use "_" for a space
Gotta love the wiki (ofc replace the drive numbers/letters with your own)
