Yes, normaly it will say whatever the part number is, luckly you also see who made the drive, so just hit the up and down arrows till you see the drive you want the OS to be on highlighted (i think it's yellow).... HIT <ENTER>
But general sequence of events when instaling windows goes like this:
The disk goes in... waiting.... waiting.... F8... waiting... enter key... waiting... select sometihng... enter key... enter key some more.... waiting... waiting... waiting.... waiting... napping... waiting... waiting... enter key... waiting... restarts... defrag... set some settings... DONE
Now, remember to burn all the data from hte old drive if you wana keep any.
And time for me to ask you a question... What interface are the drives? Both SATA? If not please show us what interfaces the drives run.
Example... the rig in my sig goes like this:
*Floppy Controler --> Floppy Drive
IDE chanel 0 --> 160gb drive --> 80gb drive
IDE chanel 1 --> DVD-Burner --> CD-Burner
*ICH5R raid controler thingy --> 2x80gb drives in raid 0
SATA 0 --> seagate 7200 rpm, 8mb drive
SATA 1 --> seagate 7200 rpm, 8mb drive
