I admit it. One of the things that caught my eye recently is a feature included in Windows 7 Professional called "Virtual PC". Simply put, that mode was designed so that legacy XP/IE6 applications could run under Windows 7 for businesses who still have legacy applications. My intention, however, was to have a couple of copies of Windows XP on it, with the various versions of Internet Exploder on it, not to mention some of the other Linux distros. After all, under Windows 7-64 bit, I have 8GB of RAM, my core 2 duo 6600 should be powerful enough, right? So, I thought I would start off with a Windows XP install. Should be straight forward, right? Slight problem, I can't boot off the damn thing. Tried a few variations.... nothing. WTF? Turns out this PEBCAK was trying to install XP from a service park CD instead of a install CD. (oops). After that minor mishap, XP is installing fine. What I am wondering is if I can reuse the same Virtualbox VDI images under Ubuntu as well as Windows 7.
