I just bought a nettop. It came with WinXP Home. I first installed Win 7 on it. I wasn't that happy with the performance so I decided to go back to XP. I am using an external dvd drive and a Win XP Pro disc.
I boot from the dvd drive and during the install get this error:
Setup did not find any hard disk drives installed in your computer.
Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program.
Setup cannot continue. To quit Setup, press F3.
This is the nettop in question: http://www.newegg.com/Product/Product.aspx?Item=N82E16883103228
