Can't boot windows after BIOS Update

[Angus Wallace]

I have an Asrock 970 Extreme3 r2.0 Motherboard, And an AMD FX-8320 CPU. I recently had some issues with Crashing/BSOD on Windows 8.1. I read that an outdated BIOS could be causing my problem and decided to update it. Now I get as far as the Windows 8 boot logo + wheel and then the screen remains black.

Go into the BIOS reset the settings then reconfigure. It may have set them to defaults

I loaded default settings in the BIOS menu, But it sill doesn't make it past the boot logo, it is a black screen with the "Eng" and wifi icons flashing in the corners every 10 seconds or so. For this reason I attempted to boot via my Windows 8 disk and repair my OS, I was able to get to the Repair screen however when I attempted to repair it I got "An error occurred when repairing Windows. No changes were made". Would this be a Windows issue for this reason or would my BIOS still be to blame potentially? Considering it was the reboot after the BIOS update that went wrong.

Try clearing your CMOS.

I tried to just now, it didn't seem to work. I removed the CMOS battery from the mobo for about 30 seconds. If I'm not mistaken my CMOS would be cleared from doing so?

it's best to leave it out for 5-10 minutes.

I've discovered the apparent issue, As it turns out the BIOS update reset my Boot order, Booting from my 1 tb hdd instead of my SSD with the OS I'm currently using on it. I'm guessing there is still a broken version of windows on the HDD and that's what I was seeing. However I am unable to permanently select my SSD as #1 boot option, It simply doesn't detect anything apart from the HDD and CD/DVD drive, Any help with this? I am able to manually boot from SSD now though so it's a start.

disconnect all drives but the SSD, then try.

Thats exactly what resetting the BIOS / removing the battery does. It resets everything inc the bootdisk. And time. Thats why I said to reconfigure the BIOS

Enable UEFI and secureboot, if they were enabled before

Go to boot options in your bios menu, and hit delete boot options. Select the hdd drive that has the broken windows 10 os and delete the boot option, then format the hdd in disk management, then try re-installing windows 10 to the hdd. Hope this helps
