Thanks everyone who responded. Your helpful suggestions are appreciated. Being new to BSD I was struggling a bit with some of the command line differences to linux, but when I took a look at fdisk, it showed me that the MBR partition ('slice') id was A5 and not A6. Wierd. I simply changed it to A6 et voila! It's now working fine.
Once again, thanks for the suggestions. This thread is now closed.
