unfortunately my solidworks 2009 and autocad 2009 does not work with windows 7. which was the main reason for the new computer. plus figured with the old OS, XP, all softwares work with it already. will look at the dual boost installation now. cant seem to get to the XP installation part that allows me to delete all the partitions. even set the startup on the BIOS to startup on the cd and not hard drive.
