电脑是ubuntu和windows双系统，忘了是由于断电还是怎么回事，开机后进入不了windows系统，直接黑屏卡死。还好能进入ubuntu系统，打开文件系统你会看到windows所在的盘会有挂载错误。

Error mounting /dev/sda3 at /media/user/Windows：Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sda3" "/media/user/Windows"' exited with non-zero exit status 14: The disk contains an unclean file system (0, 0)  Failed to mount '/dev/sda3': 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.

网上也能查到有类似问题的文档，可能原因：上一次使用win10后使电脑睡眠，没有完全关机，这次开机直接进入ubuntu系统，访问win10磁盘报错

解决方法：

1. 在终端输入如下命令，查看分区挂载情况

xx@pc:~$ sudo fdisk -l

上半部分/dev/sda 是windows系统，下半部分/dev/sdb分区是linux系统 

先是尝试修复windows所在的分区sudo ntfsfix /dev/sda3

xx@pc:~$ sudo ntfsfix /dev/sda3

发现即便是ubuntu下root账户也没有权限修复。。。。

但网上有很多人到此得以解决（若解决可以跳过下面的操作）

2. 紧接着进行只读挂载

sudo mount -o ro /dev/sda3 /media/cbdyzj/操作系统

再尝试重启进入系统
