Hi,
I tried enabling the ultra fast boot option and then it cause that none of my SSD can being detected anymore. So now I can only boot into BIOS setup instead.
The fix way is only disabled the ultra fast boot option and then my drives detected, and system is able to boot into win10 os.
But I really want to use this option, any suggestions??

Dear Toukon,

Greetings, this is ASRock TSD.

This symptom may be more relate to the SSD format.
After enabling the fast boot, system will set CSM to disable and the entire MBR format disk will be undetectable.

For this case, we would suggest converting your SSD to GPT format and then check it again.

Thanks!

All the best,
ASRock TSD
