</div></div>An even easier route, which would avoid the mapping, would be to swap<br>
the cables on the two drives. Then Winblows would always be !first!,<br>
just like it wants to be. You linux drive doesn't care where it is. Grub<br>
will go on the second drive, with its "root" at (hd1,0).<br>
You just have to remember to set the BIOS to point to the correct drive<br>
first.<br>
