Hi I have been searching the forums ( and the web in general) to see if this is possible. There are similar questions posted but most revolve around a second partition as a data disk ( which I gather is posssible) rather than as a separate OS partition (which may not be). I have set up a triple boot on my MacBook Pro..OSX, Windows XP sp2 and Vista. All are accessible at boot time ( XP is accessible through the Vista loader as a "previous version of operating system"). All are available in VMWare Fusion in a similar manner ( e.g load bootcamp partition as virtual machine and access XP through Vista loader). I am considering migrating to Parallels ( for various reasons) so I would like to know if his is possible in Parallels I can't seem to access the XP bootcamp partition through Parallels thus far. Vista boot camp partition will load but XP wont. I have tried to set up a separate "boot camp virtual machine" looking to the XP partition but it says "operating system missing". If I try to access it through the Vista boot camp via the Vista loader it comes up with Hal.dll error. Is it possible to access both the Vista and XP bootcamp partitions as virtual machines in Parallels or can i just access Vista? best wishes
