i am on a hp pavilion dv4000 and i have an external hard disk western digital 160GB
i installed linux mint 4.0 and i had your same problem: error 21 when the hard disk is not connected...
my question is : if i change hd0 in hd1 in boot loader options when i install mint, grub will be installed on the external har disk right???
because i'm not sure this will work for me because my laptop can't boot from USB
can anyone help me??
