Help - Cannot get into Z170-A PRO BIOS or BOOT

[Gerdes88]

Hello.

Yesterday i recieved my new MOBO, Z170-a PRO with my also new CPU i5-6500. Unfortunately upon startup i got BSOD, even though all the hardware seem to work as it should according to the BIOS' Hardware monitor.

After alot of struggling i read that i could just reinstall windows to fix it. So that is what i did. Atleast untill i realize that the USB gives the Load Error message. Which i think is an issue for the MOBO not properly understanding the USB stick.

So in my attempt to make the MOBO understand the USB stick properly i accidently deactivated all the USB ports, which means the keyboard isnt being read and therefore make it impossible to go into the BOOT setup or the BIOS. So i tried putting a USB to PS/2 adapter on the keyboard, but it doesnt work - no reaction at all...
So when i start my computer up it just says "BOOTMGR is missing. Press Ctrl+alt+delete to restart", which i cant even do...

So now i cannot do anything and have run all out of ideas... What do i do????

Try resetting the bios/cmos.Its done either by a button on high end motherboards or a jumper on others.You might want to consult the manual

Reset the BIOS, that would enable the USB controllers again, and then try plugging the USB stick into a USB2 port, that might help with the Windows installation, because it doesn't like certain USB3 controllers.

I managed to reset the BIOs by taking the battery out. Then i found the MSI win7 smart tool that has the drivers necessary for win7 to be installed. So its all working now. thx a lot
