|Many laptops nowadays use a SATA hard drive instead of the more traditional IDE drive. The problems with SATA drives is sometimes the cards used to read them aren't recognized by the Windows Vista DVD. In this case you have two choices:|
A) Go to the website for your computer manufacturer and download the driver for your SATA/chipset, put it on a USB key or a separate disc, and load the drivers when you use the Windows Vista DVD
B) Go into your BIOS settings (usually by pressing Delete when you start the computer, or F2 or F10) and change the SATA mode from SATA, RAID or Storage to IDE.
This is assuming that your hard drive is readable in the first place.
