Comment 11 for bug 76976

Using herd 2, I was able to work around this problem, by getting rid of
grub/MBR using:

dd if=/dev/zero of=/dev/hda bs=1024 count=1024

All other attempts including manually partitioning still resulted in the error.

Unfortunately, now I'm getting a different error much further into the install - but I'll file that in a seperate bug.
