Solaris mboot is installed into MBR - it chainloads boot loader from boot sector of active primary partition which is Solaris one, since the installer makes sure that Solaris partition is set as active at the end of the installation. In your case, you could either chainload your other Grub boot loaders from Solaris Grub or you could reinstall your Grub into MBR and chainload Solaris GRUB from there. Cheers, Jan
