I have a Lenovo Thinkpad T430s with Ubuntu 15.04 and Windows 8.1 installed. For a long time, everything worked fine. However, the last time I tried to boot into Windows from GRUB, it showed the Windows boot screen, and everything was fine. After the boot screen, the screen goes black.
I believe I disabled fast-boot in Windows. However, when I attempt to access the Windows files, a window comes up saying:
Error mounting system-managed device /dev/sda2: Command-line `mount "/media/sda2"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0). Metadata kept in Windows cache, refused to mount. Failed to mount '/dev/sda2': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option.
What do I do? Has anyone had this problem? Edit: I forgot to mention that I have to boot into Ubuntu using upstart mode. If I try normally booting into Ubuntu, it puts the computer in "emergency mode".
mount /dev/sdxy /mount/point -o roand recover your data. – Panther Nov 19 '15 at 19:55
