AsRock B450 Pro3 Ultra Fast Boot not working

[jonqqh]

Hello,

 

I have an AsRock B450 Pro3 and whenever i turn on Ultra Fast Boot, Save Changes and Exit, it just boots into the BIOS again. I did notice a change and it was, that my boot order has changed: It only displayed BIOS instead of my SSD and HDD. Support is greatly appreciated. Thanks

Then change the boot-order again.

Reset BIOS or remove cmos battery.

Have you installed Windows in Legacy/CMS mode or UEFI mode? I'm guessing ultra fast boot will enable UEFI mode, and as such will not recognize any OS installed as Legacy/CMS.

Yeah, WIndows is installed in Legacy Mode. I guess that's the answer to the problem

Forget that ultra fast boot modes - they may work or not (mostly not) depends on installed hardware. Stupid usb device can prevent working it proper. In Asus or old MSI boards it working more or less, but for example on new MSI boards (I tested three of them) it not working no matter I change.
