Hey, i have bought a DVD Burner, with lightscribe fore a few days ago, and it worked fine, before i sat in another older dvd reader i have had before. After i had inserted the new dvd reader i dident find the dvd burner and dvd reader in the system, not in the bios either. I have tried to install it again, i have also tried to change slave/master function, nothing work. And i now the cd burner works, because i have tested in another computer i have, and it worked fine there. I have also tried to use wipe disc. And trie to re-install xp, but since the bios dont find the drive, yeah, you can figure out the rest
