I have a similar problem, and I'd asked for help:

I didn't run fdisk at all after completing the Plan 9 installation,, it
said it was writing a kernel to the partition, I selected the option to
make 'this' the default plan 9 partition, selected reboot and from the
DOS prompt immediately tried plan9\b. There doesn't seem to have been any
chance for the boot partition to get overwritten in this case.


presotto had suggested:

I tried that and had the same problem. I'd replied to this mail but the
answer probably got lost,, our internet gateway was down all of last week.

Any ideas?
