Hello, i have an ACER Travelmate 292LMi. The original Dvd-Rom that was with my acer broke down and i switched it with a NEC 7550A. Now i want to format my pc and i noticed that primary dvd is still the one i changed(the one broken). First boot device is the cd-dvd but the format procedure doesn't start. How do i change the primary disk drive to the new one?(NEC)
Thank you
