Boot from your Solaris Installation CD or the BeleniX live CD and get a
shell prompt. If cNdNtNsN is the slice containing your solaris root
filesystem, execute the following commands.

# mount /dev/dsk/cNdNtNsN /a
# cd /a/boot/grub/
# cp menu.lst menu.lst.bak
# installgrub -m stage1 stage2 /dev/dsk/cNdNtNsN

That should reinstall grub on the MBR. Restore your old menu.lst if you
had any customizations in it.

Cheers,
Ananth
