Loading 10.0 on old HD

[Al Plant]

Aloha,

Where can I find a "how to on" loading the new 10.0 Freebsd onto a HD 
which already has a previous version of 9* 8* 7* or Windows on it.

There is an error I think from the old boot loader from the original OS 
on there.

Error:

  init
The process stops with:
/bin/sh  ON /etc/rc

Then goes to single usr mode:
How can I clean the disk from whatever is stopping the process of 
loading the new Loader and OS 10.0

I have 7 of these HD's I have tried.

Thanks..  any help appreciated.
