If you have dual boot in your laptop with Linux and Windows installed, you might face this kind of problems, when windows is not properly shutdown. Generally, from windows 8 and onward “Turn on fast startup” is checked by default to reduce boot time in windows. This increases the boot time but for dual boot who specially works on Linux face this error if they didn’t shutdown windows properly.
Now, Lets solve the problem without restarting your computer. It’s easy you just need to know one simple command.
sudo ntfsfix /dev/sda2
ntfsfix repairs some fundamental NTFS inconsistencies, resets the NTFS journal file and schedules an NTFS consistency check for the first boot into Windows.
Most of the time it works but sometimes in windows bootable file it might not work.
