Dialog box tells me there's a missing driver when installing 64-bit version of Windows 7

I'm trying to install Windows 7 64-bit on my computer (ASUS P6T Deluxe V2, one 80GB HDD and two 1 TB HDDs). When I'm supposed to select whether I want to Upgrade or do a Custom install, I get a dialog box telling me:

Load Driver

A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.

Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step.

I've tried to reach this step using a 32-bit installation disc, but that doesn't generate this message at all. Through the command windows (shift-F10) I can reach all of my drives, including my optical drive, without any problems--so what kind of device driver is it the installation wants? I've tried all the obvious drivers on the CD that followed my motherboard, but I can't seem to find the right one. The problem is that I don't know what device I'm supposed to load the drivers for in the first place.

Can anyone help me?

Edit: It turned out that my downloaded image was corrupted. I borrowed a DVD from a friend of mine, which worked!

Solution 1:

I've had this exact error message, and it was caused by some sort of error on the DVD that I burned (I had burned the DVD at the fastest supported speed).

I solved it by using a new blank DVD and burning the ISO at the slowest speed that the DVD burner supported.

I think when I burned the original DVD, it verified correctly. For some reason, it seems that the Windows 7 installer is more sensitive to media errors.

Solution 2:

Get a USB DVD-drive and try installing from that. If you can't or it doesn't work:

Put the installfiles on a USB flash drive, that way you shouldn't have to load any drivers.. If you need to know how to do this, Google (with Bing :)) for "Windows 7 install from usb" or something, should be many guides that show you how to do this..

Have fun! :)
