dual boot
not, as you posted “duel” boot. Microsoft operating systems like to take first place in the startup, but with a verion of it already installed many linux distributions can be installed second. Try linux Mint. It should detect that you have a Microsoft product installed already and then give you a dual boot option on start up. Works plenty nice on my XP / Mint Thinkpad (R52). See if a search for “dual boot Mint” gets you to a happy and blessed place.
lol.. good catch, sorry about the misspell/typo :p
