Parallels won't boot Boot Camp

Have been using Parallels Desktop 5.0 for quite a while on MBP. Got new MBP, used Winclone to copy over WindowsXP partition, installed new Mac drivers, rebooted 3 times to be sure. Boot Camp works perfectly fine as does all of the Windows software. Parallels however hangs with the message "Trying to boot from Primary Master IDE drive ..." Used uninstaller to totally uninstall and reinstall parallels. Same problem. Went back and checked and Boot Camp still works fine. Running 10.6 on new MBP. Any help would be greatly appreciated.
