On the advice of a friend who knows something about Gentoo and Sabayon,I modified the entry for Mandriva in /boot/grub/menu.lst as follows: title 'Mandriva Linux 2007' root(hd0,4) kernel /boot/vmlinuz root=/dev/hda5 initrd /boot/initrd.gz
Whenever you install a new system as the additional one, the new system may not add entries for the existing one. The shortest step is to copy and paste the *relevant* entries from the /boot/grub/menu.lst of the older system to the menu.lst of the new system. This is assuming that both use GRUB as their boot loader.
If I recollect correctly, then Mandriva's favourite boot loader is LILO and not GRUB. They don't accomodate each other, though on the net some experts claim to have done it.
The easier way out is to load the Mandriva boot CD and re-install the boot loader as GRUB. Then add relevant entries of Sabayon's menu.lst into the new menu.lst of Mandriva.
