DVD-RW isn't recognized by Windows
My HP came with a DVD-R drive and a CD-ROM drive. Today, I took out the DVD-R drive and replaced it with a DVD-RW drive.
I hooked the DVD-RW up the same way the DVD-R was.
But for some reason, Windows does not recognize the new drive, and now it won't even recognize my CD-ROM drive, which I didn't touch! I checked the connections and everything, and nothing is working!
I have the DVD-RW hooked up with the jumper set on 'Cable Select'.
I think perhaps the problem is that I'm still running on Windows SP1. But when I try to install SP2, it gives me an error message after installing saying 'Access Denied'. Plus, when I try to install other things, it tells me I need to be the system administrator to install them, even though I am. How do I fix these problems? Are they related?
Any help at all is appreciated.
