installing mandriva on usb hard drive.
Hello Linux experts can someone help me please? I have a 250 gig usb hard drive. I have formatted it, and split it into 2 partitions. I would like to install Mandriva 2010.1 onto the first partition. Do I connect the hard drive (usb) after Windows has finished loading and then restart after altering the boot-up configuration? Or do I boot-up the Mandriva disc, then connect the usb drive? If some kind soul can give me the correct sequence I will be very grateful. I am really keen to get Linux running and would appreciate any help, nothing too techie if you don't mind.
