I’ve purchased a brand new Windows Vista machine but I want to install Windows XP on it as well. I’ve heard that to dual-boot Windows XP needs to be installed first – is this true?
Unfortunately once you have Vista installed on your machine you cannot install Windows XP and easily set it up to dual boot. If you have Windows XP installed first, it’s relatively easy to install Vista as a dual-boot partition, but if you try to install Windows XP now, it will overwrite your Vista installation.
One option you might want to consider is running Windows XP in a virtual partition. You can download software like Microsoft Virtual PC to set up a virtual machine which can run Windows XP for you in a window.
Hope this helps.
