In Windows 8 and 10, Microsoft added a “Fast Startup” feature that saves a state of the computer to disk. This is like Hibernation, which for a while has prevented Linux from mounting a Windows partition. This new feature makes hibernation much more frequent, so dual-booting machines will start to see this much more often.

In this source, how to disable Fast Startup is explained. I also suggest disabling Hibernation when you close the lid, since Linux will boot when you turn the screen back on.
