Have you been wondering whether you can run Vista and XP on the same machine by means of upgrading XP, or are you looking for a way to switch between Windows XP and Vista because of issues with legacy software, look and feel, testing, curiosity, etc.? In this article you will find useful information about upgrading from XP to Vista. This information is also valuable if you are running Windows XP and want to install Vista beside XP in a dual-boot configuration.
In a dual-boot configuration you install Vista side-by-side with Windows XP, or vice versa. Upon booting your computer you can decide which operating system to start. You will be shown how to setup a dual-boot with XP installed first, how to dual-boot Vista and XP with Vista installed first, and how to revert a dual boot configuration back to Windows XP or Vista only.

If you are considering upgrading your computer from Windows XP to Vista download the Windows Vista Upgrade Adviser, a small program which is helpful to you in determining whether your computer is ready for Windows Vista. The tool scans your computer and produces a comprehensive report of your system’s hardware and software Vista readiness including drivers. Any compatibility issue detected has a tip of how to resolve it, and the Windows Vista Upgrade Adviser tool makes a recommendation which edition of Vista will best suit you.
Here’s the link to the overview of the Windows Vista editions along with their price tags. Check out the Vista upgrade paths from previous versions including Windows XP along with the available installations options: A clean install by means of transferring programs and data manually always works, but some upgrades can additionally be made by means of in-place installations.
Please note by the way that with Windows Anytime Upgrade you can upgrade Windows Vista to a more powerful edition of Vista any time later when you need the better version. In case you have special hardware and you are unsure whether it works with Windows Vista check the vendor’s website or visit the Windows Vista Compatibility Center.
You find the different Vista editions’ varying hardware requirements including RAM, processor speed and hard disk capacity in the “Windows Vista recommended system requirements”. As a rule of thumb you should at least double Microsoft’s “minimum” requirement for good system performance and acceptable user experience.

In a dual-boot configuration you install Vista side-by-side with Windows XP, or vice versa; upon booting your computer you can decide which operating system to start. In order to configure your computer for dual-booting Windows Vista and Windows you have to have one partition for each operating system. You will be shown how to create free space for a second partition without third-party tools in the sections below. We then install the second Windows onto the free space, thereby creating the second partition.
Please note that
• in a Windows XP/Vista dual-boot setup programs need to be installed once again for the second Windows, be it either XP or Vista.
• although data on either partition is being shared, you may opt to create a third partition for data only to facilitate removal of XP or Vista.
