How to disable Fast Boot on Asus zenbook for EFI boot
The option that's critical to disable is not the "fast boot" feature in the firmware; it's the "fast startup" feature in Windows. This feature turns shutdown operations into suspend-to-disk operations, which means that the filesystems are left in an inconsistent state, which is a recipe for disaster when you dual-boot. See this Windows forum page for details on how to disable this feature.
I know less about the Intel SRT feature, so I can't really comment on it.
