Can I install windows XP on the same laptop that I already have windows 7? I need windows XP to be able to use my old HP printer.
If you have Windows 7 Pro, Ultimate or Enterprise your best bet is to install the free Windows XP Mode, which will take care of HP issues: http://www.microsoft.com/windows/virtual-pc/download.aspx
It is much less hassle than dual booting and far more convenient. XP mode is free.
