if it were a primary partition you'd use
disk/format -b /386/pbslba /dev/sdC0/9fat
however, as an extended partition i'm not sure
you can actually boot from it. which boot loader
were you using before? i'm not sure i know of any
that will boot extended partitions.
disk/mbr -m /386/mbr /dev/sdC0/data
will install a new mbr, as andrey said, but that
shouldn't be necessary -- the windows one is
typically fine.
how were you selecting between windows and plan 9?
the windows boot menu perhaps?
