This question already has an answer here:
my LapTop, that runs on Windows 10, now doesn't start anymore. So I wanted to save all my files by USB-Booting Ubuntu 16.04.1 LTS before sending it in for repair.
But when I try to access my drive in Nautilus it gives a lengthy dialogue:
Unable to access “255 GB Volume” Error mounting /dev/sda2 at /media/ubuntu/CAEED374EED356F3: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=999,gid=999" "/dev/sda2" "/media/ubuntu/CAEED374EED356F3"' 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.
How do I mount that drive as Read-Only? Due to lack of disk space I can't install Ubuntu without erasing the stuff, that I actually want to save.
A graphical solution in nautilus or something would be much appreciated. Else could you please tell me exactly what I need to type in the Terminal.
