Hi,

thanks for the answer.

Thanks for the pointer.

I see.

Yes, I already guessed that I will need separate / (containing /etc ...),
/usr, /var for a dual boot. What I wanted to achieve is to have a single
boot menu. As the current situation stands, I will need two /boot
and manually set up an entry in the default one -it would be the
32 bit Fedora- so it boots another grub (that boots the 64 bit Fedora).
An entry similar to one that boots into a Win* should do, at least I hope.
