I have a Dell Dimension 8200 running Windows XP SP3, and I specifically partitioned my hard drive so I could install Windows Vista (2 Operating Systems, XP and Vista at same time is what I wanted). When I run the Vista Installer, it keeps asking for me to locate a driver for one of my CD Drives in which I do not have. I don't even know if I have a driver disk for it. How can I get by this stupid thing? It wont continue without knowing the driver.

what driver exactly is it asking for?

are you following a guide, see similar

I dont use a guide because I think its pretty much self explanatory, i already preformatted windows xp with its own partition to prepare for installing vista,

As for the CD Drive, it is non-factoy standard, we bought it later on because our old drives suck. I had to disable the bay above it too, so this is the only one I use.

Model: SONY CD-RW CRX320E NYK4

Thats exactly what it looks like

Oh and also, if i attempt to install vista with the top drive (Just to see) it will still ask for the bottom drives driver.
