I recently performed a repair install on my XP professional system. After it finished and I applied all updates, I noticed that the DVD-rom drive I have in my computer wasn't working and isn't in the device manager. However, it works fine before going into windows and is even recognized by the bios. I already tried that deleting the lower level and upper level filters and that did nothing. I also tried installing new drivers but since windows can't see the drive, it won't let me. How can I get my DVD-rom drive working again?
