Disk mount error is common in Dual boot and we often face this issues. The drives used in Windows are not easily accessible from other OS. However, it is easier to fix this issue with just some commands in the terminal in Ubuntu. I am using Ubuntu 16.04 and this works fine in previous versions of Ubuntu as well as other Linux OS.
Steps to Solve Disk mount error in Ubuntu
Click on the disk which you want to mount or the disk which has mounting issues. For me, I have mounting issues with my Backup drive.
A dialog box will pop up addressing the mounting errors. Remember the path of this disk. In this case, the path is /dev/sda7.
Now, open the Terminal (shortcut – Ctrl + Alt + T ).
Type the following syntax:sudo ntfsfix /dev/sda7
(in this case of Backup drive the path is /dev/sda7 and it varies from drive to drive) and press Enter. You will be prompted to enter the password. Enter it and your disk will be mounted.
There are also other techniques to mount the drive but I prefer this one as it works every time with no errors.
Permanent Solution to solve disk mount error through Windows 8/ 8.1 /10
In Window 8/8.1 and 10, Microsoft has significantly reduced the boot time which previously slows the bootup time. This new feature is called Fast Startup. Windows fast startup process works similar to the hybrid sleep mode of previous versions of Windows. By saving the OS to a hibernation file, it makes your computer boot up faster than before, thus by reducing the boot time. Fast startup is enabled by default in Windows.
Fast Startup is the cause of disk mount error in dual boot. After disabling this feature, there won’t be an issue of disk errors in Ubuntu or other OS in dual boot.
How to Disable Fast Startup in Windows?
Go to the Windows search panel and type Power. It will show you different options. Select Change what Power button do.
You will be directed into Control Panel’s Power Options. Click on Change settings that are currently unavailable.
Now, you will get an option to disable Fast Startup below. Uncheck Turn on fast Startup and click on Save Changes. After doing this you won’t have to type Terminal the command ( which I taught above) for each drive to mount in Ubuntu.
