[SOLVED] Windows not directly booting, only via boot override in the bios.

[RexDomi]

Yesterday i aquired a 6700k and a Z170 Pro Gaming from Asus. This motherboard finally had a M.2 slot so i popped in my 980 Pro and installed Windows on it. But when i start up my system i am always prompted to my bios and not booting into windows directly. In the bios however i can load windows from that drive via boot override but that is kinda annoying. I am using the latest bios and drivers for the motherboard. I found some similar topics on various websites but nothing seemed to help me. Anybody got some ideas what else i can try?

Here is the link to the pictures i have taken of my bios settings. Maybe someone can help me that way.

Thanks in advance RexDomi

hi, you have missconfigured your bios
windows is installed in UEFI mode (as it says windows boot manager in your boot order)
but in CSM you have boot from storage set to legacy, switch it to UEFI or disable CSM,
that should make it bootable

I've tried both of the options you mentioned and the ohnly thing that happened is that the regulkar 980 pro listing disappeared and it switched to my other monitor. Downloaded the Samsung Magician Tool and updated the firmware but still no luck.

It has to be something in the bios tho. Thested the system with a sata ssd didn't boot directly, tested that ssd in another system and that booted just fine. I have reflashed the bios and cleared the cmos as well. Could this problem be caused by a dead cmos battery?

I just figured out the problem and will share it with you just in case someone stumbles upon the same issue. It was the combination of my pump being pluged in to CPU_OPT which lead to a CPU Fan Error und the setting "Wait for F1 if Error being enabled. Switched that to disabled and now my PC boots just fine.
