Hi, I'm running on Windows Vista 32-bit. Anyway I had two partitions, C drive which has the main Vista OS. And another 40gb drive known as D drive named "Backup". Well "Backup" D drive was a logical partition, when I was about to delete it windows warned that other programs might be using it, but I deleted it anyways. Why? because I wanted to dual boot Vista with Linux, having the empty 40gb left empty after deleting the D drive partition. I wanted Linux so I could do C++ programming under it for university work. So anyways when I restarted my machine Windows could no longer recognize my 2 different DVD drives (one is read only, the 2nd one can burn). That is, my 2 DVD drives are not shown anymore: When I goto device properties I see: The Phillips and TssTCorp are my DVD drives. In it's properties, all of the above devices have error code 39: I have tried deleting the 3 devices, and scanning for hardware changes so Windows automatically installs new fresh drivers but instead I get this error after its attempt to re-install the 2 DVD drives: Please help!! BTW before I deleted the (D) Drive "Backup" logical partition, everything was working just fine. Thanks for any help! PS: It's a dell, and installing new DVD drive firmware updates is useless when it can't "see" that the 2 DVD drives exist.
