裝完parallels後,重開機後無法進入windows？

請問大家
我裝完parallels之後
重開機可以進入到開機選項
選擇windows後卻進不了系統,畫面是全黑的
請問有什麼解決的方法嗎

我自己有看到parallels的文件,裡面是說
Troubleshooting
When booting into Boot Camp, you may get the black screen with the choice of two
configurations:
Parallels
Windows XP Professional (or Home, it depends on your version of Windows XP).
You may get an error message.
1 Restart your Macintosh computer and boot into Mac OS X.
2 Start Parallels Desktop. Start the virtual machine which uses Boot Camp Windows
installation as a bootable disk. Wait while the guest OS is fully loaded and shut it down.
3 Try to boot via Boot Camp again. Booting should be successful.

我有按照上面的方法去做,還是無法解決
請問大家有方法可以解決嗎？
謝謝大家
