my issue is so like other posts but a smidge different. my dell 1735 has two hdd bays. i stripped my original hdd and loaded it with ubuntu. i placed it in my secondary bay and hooked it up. i recieved another hdd from dell, preloaded with vista and put it into the primary "original" bay. How do i boot up my secondary hdd? i think i may be missing the forest through the trees. thank you. sincerly, tommybee.
