Pavilion Media center m843f switching to blue ray drive causes "Unauthorized Change" error

‎03-21-2011 09:38 PM

Hey All,

 

I bought a Pioneer BDR-206Bk (Blu-Ray burner)and wanted to switch out the pre-installed lightscribe dvd burner. After I rebooted, it would not let me log in, instead it gave me this error: "An unauthorized change was made to Windows (0xC004D401) "  It let me go onto the internet and try to figure out what was wrong.. but after I closed the browser it logged me right back out... Upon re-loggin in.. the same thing happened. I re-installed the original drive and the computer camer right up..

 

How do I go about installing this and having it let me back into the computer? 

 

Thanks.
