*Although the Windows 7 DVD driver not found error can occur with some OEM discs, it is more common with burned backup discs. If you are using a burned disc, try cleaning it. Also, make sure that it’s scratch free. After you have done this, try installing Windows again.
*Another solution that you should try, is burning a new copy of Windows 7 at a slower speed. Today’s DVD writers are pretty fast. Sometimes, burning DVD’s at max speed can cause errors. Burning at a slower speed assures a quality DVD burn. Create a new Windows 7 disc and try to install Windows.
*Install Windows 7 using a USB flash drive. This is probably your best bet for getting around the error. Because Windows is detecting some type of incompatibility with the DVD drive’s drivers, a USB flash drive installation is an ideal workaround.
*If you have never done an installation using a USB flash drive, don’t worry. It’s just as easy as installing from a disc, you just have to change a couple of settings. Please note, you will need a USB flash drive with enough capacity, preferably 4GB and up, as Windows 7 is approximately 3.75GB in size.
