Boot your installer disk and choose option 6, then say "yes" to mounting file
systems under "/a" .
(If it does not ask to mount existing file systems then the rest of this will
not work.)
Now type (after it boots):
# format
Look at the output that the format program gives to determine the name of your
HD:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1d0 .drive type unknown>
/pci at 0,0/pci-ide at e/ide at 0/cmdk at 0,0
1. c2d0 .DEFAULT cyl 6120 alt 2 hd 255 sec 63>
/pci at 0,0/pci-ide at e/ide at 1/cmdk at 0,0
Now hit CTRL-C to exit.
So for the above example you would type this:
# installgrub -m /a/boot/grub/stage1 /a/boot/grub/stage2 /dev/rdsk/c2d0s0
# sync
# reboot
(Don't forget to eject your Installation Disk)
Now the Grub menu ought to appear and will automatically boot if you don't
touch anything.
