I recently replace my bad DVD drive is it went bad in my macpro intel 2.8 quadcore I am trying to install win 7 bootcamp but it won't work. I have a trial of Parallels and that works so I know its not the disk. I have tried bootcamp on my new MBP and it seemed to work well got to windows screen. I have several internal drives on my SL and ML I ejected all of the drives except my original drive which I wiped and re installed SL and then partitioned this in bootcamp. Bootcamp won't let me install the updates and every time I have tried to restart with bootcamp the computer hangs on the apple logo. also pressed option boot up from windows and get the no entry sign. I have tried this method 15 times and it is the same each time. I have attempted this also with ML (with the updates files on a usb disk)and managed to get to the no bootable device screen and that's it. I have tried to make a iso and could not get that to work (converting .cdr to iso) Could some one please help!.
