In v10.2 during the installation process there was an entry in the grub 
setup sequence where you could choose which HD was going to be the first 
HD and be "the booter". In 10.3 this is no longer available and the 
installation process decides where the boot info will be placed, and it 
can stuff it up by putting it on the second HD - which it did in my case 
and it took me a while to figure why the system wouldn't boot. After 
altering the device.map and the entries in menu.lst I got the thing going.

Ciao.
