/dev/rd is usually a ramdisk. However there seems to be confusion in the 
linux driver world, with raid devices using it as well.

c0d0 is controller 0, disk 0, no partition (the raw disk)
c0d0p1 is controller 0, disk 0, partition 1.

Grub needs to be installed on the raw disk, not a partition. Probably the 
Ubuntu installer couldn't figure out for itself where to install the boot 
loader, or perhaps it thought that it didn't need to. Only examining 
/var/log/installer/syslog on the installed system would tell us that.

Cheers, Chris.
