Installing Windows XP on a HP DV6500 series Laptop. This tutorial covers the process of installing Windows XP on an HP dv6500 series Laptop. Currently, most HP Laptops are being shipped with Windows Vista, and there is minimal driver support on the HP website site for those who want to downgrade to Windows XP. Hence the necessity for this tutorial. We will be using nLite to create a remastered Windows XP installation disk with integrated SATA drivers, so having a working CD Recorder is essential. I would also recommend having a USB flash drive handy to hold the additional drivers that will be installed after XP installation.
