[nycbug-talk] broke bootblocks

[George Georgalis]

I have a hosed system.

It has FreeBSD, WinXP and NetBSD on slice 1, 2 and 3; plus
Linux on some extended partitions. The last OS I installed
was WinXP. I don't really care about the Linux install,
but I'd like to get this thing booting slice 1, 2 or 3.

I tried "fdisk -B wd0" so I could boot into the other non XP
slices, but it only sees Linux as bootable, and that doesn't
work.

Below is the output of netbsd "fdisk wd0 ; disklabel wd0"
from the netbsd 2.0.2 cd.

How do I boot this thing?
