When using Linux as the dual boot option with Windows 8/8.1/10, users often get an error message while mounting their NTFS partitions, such as: ‘The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully’, along with other technical details of the error.
This happens due to the FastBoot feature of Windows 8/8.1/10, which keeps NTFS partitions in hibernated mode when Windows is shut down.
Once the hibernate flag is set to ‘On’ for the partition, Linux cannot mount that partition and considers it is being used in Windows.
This can be avoided by turning the FastBoot feature off. This may not cause any trouble, apart from users noticing an increased shutdown time for the Windows operating system. But they won’t mind this difference if they’re not frequent Windows users.
In Windows 8/8.1/10:
1. Open the control panel and from the small icons, view and click on Power Options.
2. Click on Choose what the power buttons do.
3. Click on Change settings that are currently unavailable.
4. Uncheck Turn on fast startup (recommended).
