今天，我通过从笔记本电脑中删除 Windows 8 进行了全新 Ubuntu 安装。我以为安装 Ubuntu 后，我将毫无问题地访问 D 盘，因为我所有的重要数据都存放在那里。但现在我无法安装 D 盘。它出现以下错误。
ror mounting /dev/sda5 at /media/nitesh/data: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda5" "/media/nitesh/data"' 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/sda5': 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.
现在我没有 Windows 8，也无法完全恢复和关闭 Windows。现在有什么解决方案吗？
