parallels 3120 要開bootcamp發生錯誤

它出錯的錯誤碼是


Parallels Desktop has detected, that Parallels Tools for Boot Camp (beta1 version) was installed on Boot Camp Windows partition. Please, uninstall Parallels Tools for Boot Camp before using Boot Camp in Parallels.


可是我確定我有用bootcamp開機 去把parallels Tools for Boot Camp 給刪掉了
我是用xp的控制台刪的 感覺是刪不完全
請問這個問題該如何決解？
謝謝的大家的幫忙!
