无法启动。 错误：无法打开\ EFI \ BOOT \ grubx64.efi-未找到

我有一个索尼Vaio双启动Ubuntu 16.04和Windows 10.这一切都是在我的Windows分区开始行动并且在启动时挂起（在我在GRUB菜单中选择它之后，它会再次显示Vaio徽标，然后坐在一个黑色的屏幕上，点上的圆点永远旋转）。 我尝试使用boot-repair来修复它。 Boot-repair告诉我关闭安全启动。 在我这样做并且启动修复后，我得到了这个错误报告： http ： //paste.ubuntu.com/26240501/ 。 现在，我的GRUB菜单中添加了更多选项，我不知道他们做了什么。 Windows分区仍然在启动时挂起。 如果我再次打开安全启动，当我启动计算机时，会弹出Vaio徽标，然后立即出现黑屏并显示标题中的错误。 然后我直接发送到一个菜单，我唯一可以访问的是BIOS设置（没有GRUB菜单）。 在Ubuntu上，如果我单击Windows分区内存，我会收到此错误：

"Unable to access 932GB volume" Error mounting /dev/sda5 at /media/millar/4484E74A84E73D54: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sda5" "/media/millar/4484E74A84E73D54"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 1). 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. 

如果我运行sudo fdisk -l / dev / sda5，我将其作为输出：

如果我运行sudo lshw，我得到：
