1. Before installing Parallels 4 for the 1st time what should I do with the 10GB Windows XP partition already set up on my IMAC? Will Parallels 4 installation set up a new(override old) Windows partition or do I need to delete the Windows partitions 1st? Or does Parallels not need the Windows XP Partition and handles in the Virtual world? 2. Will I be able to re-install my TrendMicro antivirus to protect the Windows stuff?
