Linux Dual Boot 32bit / 64bit

Hi guys,

So I have an Arch Linux Installation on my old Netbook and it works splendid ! However I wanted to try another distro (Void Linux) with 32 bit. So I installed it on another partition without installing grub. After successful installation I rebooted into Arch and updated grub with

grub-mkconfig -o /boot/grub/grub.cfg

It created all required entries, but after rebooting again when I tried to select and start Void Linux I got error messages (kernel couldnt be found etc.). Arch still boots fine.
Then I tried it the other way: I chrooted into Void Linux and installed Grub which works fine. But when I try again to update the config file to find the Arch Linux partition it gets stuck and it prints error messages.

I am asking myself now: Maybe it's not possible to have a dual boot with 32bit and a 64 bit OS ?
Could you give me a little advice here ?

Fixed on my own. Copied the /boot/grub/grub.cfg from one system to /etc/grub.d/40_custom in the other system.
Still no idea why it didn't work with the standard method which I described above, but hey ...

Copied the /boot/grub/grub.cfg from one system to /etc/grub.d/40_custom in the other system

It would be better to reference Void's grub.cfg in 40_custom, like this (replace $uuid with the actual filesystem UUID for the Void root partition):

menuentry 'Void' {
   search --fs-uuid --set=root $uuid
   configfile /boot/grub/grub.cfg
}

I would be interested to see Void's grub.cfg to see what's different. EDIT: it's probably the modules, at a guess.
