Hi, I have searched the forums, but this seems like too general of a question to find the answer to. My Windows 2000 Pro disk is only SP1. The Parallels manual says that only sp4 is supported. However, I have read posts of people instaling SP1. Wen I insert my disk, and run a Virtual machine form it, it says no bot disk is available. Is this because I do not have a SP4 CD? If so, is there a way to slip stream SP4 on a Mac? Could there be a different issue? Do I need to create/download a bootdisk? Thank you for your help.
