This could also happen if the file system is not clean because of an operating
system crash, an interrupted boot process, an improper shutdown, or unplugging
of a removable device without first unmounting or ejecting it. To fix this,
simply reboot into Windows, let it fully start, log in, run 'chkdsk /r', then
gracefully shut down and reboot back into Windows. After this you should be
able to reboot again and resume the installation.
