Disable Fast Boot on Windows 10

For those dual-booting Windows 10, it’s useful to disable Fast Boot so that you can access the Windows partition from Linux.  I didn’t notice more than a few additional seconds of boot time due to disabling fast boot.

Control Panel → Power Options → System Settings → “Choose what the power buttons do”

Bitlocker and dual-booting

If Bitlocker is enabled, Linux cannot access the Windows partition.

How does Fast Boot work?

In short, when you shutdown your PC, Fast Boot actually reboots and then hibernates. This locks the Windows partition so that Linux can’t access it.

Fast Boot SSD wear

Fast Boot just like hibernate increases solid state drive (SSD) wear, since you are dumping an image ~ RAM size to disk on each Fast Boot shutdown.
