I have this same issue, but with XP. Whatever Parallels Tools did while installing has destroyed my keyboard and mouse support when I reboot directly into Windows. I can't gain mouse control in either, but was able to access my boot camp partion through another VM, removing the kbdmgr as well as any extra programs, still no luck. Either way I boot into my boot camp partition I'm met with a flurry of driver installs that stall on the video driver or require access to user prompts I can't click. I've tried directly adding a dedicated USB mouse to no avail, this is rather disappointing as I've already had to create files merely for Parallels to acknowledge my boot camp partition's existence. Anyone have any idea what to do now?
