Asus S400CA boot priority is not available (empty)

[Joshua_06]

My Asus S400CA just installed FydeOS, after reboot the laptop just enter the BIOS and never can boot from the harddrive. I have been tried many ways, setting BIOS like many others did, such as
setting the FastBoot ---> Disabled, 
CSM-----> Enabled
Secure Boot ----> Disabled
Change the Battery CMOS
unplug & plug the harddrive 
But the problem still exitst, the laptop everytime reboot just enter the BIOS, and never show the Boot Priority option 
How to solve this problem ?

Due to our lack of testing on non-Microsoft systems, we cannot guarantee their stability and compatibility with our product. If you need to clarify the issue, we recommend restoring the system to its factory default settings, confirming that the BIOS has been updated to the latest version, and then verifying that the options can be set normally. Sorry for any inconvenience it may be caused.
