Somehow your BIOS doesn't want to boot from the hard drive.
One alternative is to download the boot floppy image and boot it.
At the boot from prompt, type "sdC0!9fat!9pcf" (no quotes),
and at the root is from: prompt, type "local!#S/sdC0/fs" (again no quotes).
At the user prompt just hit enter to use glenda for now.
If that boots, then you can try re-installing the mbr.
At a prompt, run
disk/mbr -m /386/mbr /dev/sdC0/data
at a prompt and then reboot without the floppy. (You may
want to spend some time reading the various intro material
on the screen to familiarize yourself with the window system
first.)
Once you run disk/mbr and reboot, you should see
"MBR..." print out once the BIOS decides to boot from
your hard disk. If it's not followed by "PBS..." then
you can run
disk/format -b /386/pbs /dev/sdC0/9fat
to re-install the partition boot sector. If that one doesn't
work you can try
disk/format -b /386/pbslba /dev/sdC0/9fat
which uses a different BIOS call to access the disk.
(Most BIOSes support either, very old ones support only
the first, but maybe there are more recent ones that
support only the second.)
In the worst case, if none of this helps, you can create
a plan9.ini on the boot floppy with bootfile, bootargs,
mouseport, monitor, and vgasize lines and then just boot
from the floppy. (I suppose in the very worst case even
the floppy won't help and you'll have to burn a special
boot CD, since we know your machine can boot CDs.)
