This message is caused when Windows encounters a corrupt hibernation file. You can delete the error or try to reboot using that hibernation file. Deleting the file means that anything you had loaded in memory will be gone when you boot into Windows. Occasionally, Windows seems to "hang" or "lock" when this screen appears. Try a PS2 Keyboard, a PS2 adapter for your Keyboard, or unplugging the keyboard and then plugging it back in. See the following URL for more information: http://support.microsoft.com/kb/294427
