Hello, new here. I need some help with my Z390 Taichi, My OS was Windows 10 then updated to windows 11. Everything was good until a few days ago i was playing BF6 and it crashed randomly, so i reset my pc. when it was booting back up it keeps saying Preparing automatic repair. when i got into bios and turn off "secure boot" its runs perfectly fine. Both my drivers are GPT, I have CSM turned off. |

You may need to reset Secure Boot Keys to Factory Default Once you are booted into Windows, a corrupted Secure Boot key might be the issue. Restart your PC and re-enter your BIOS, go to the Security tab, find the option for Secure Boot Keys or Key Management. Select Restore Factory Keys or Install Default Secure Boot Keys. Save, exit, enter BIOS, re-enable Secure Boot and restart. Hopefully that sorts you out. -------------

Iv done that also when i clear keys and turn secure boot on it doesn't active it, once i install key it actives and does the "preparing auto repair loop". I did notice when it sends me to the repair screen its say "continue to windows 10" but i have windows 11 installed. |

What BIOS version are you on? If it isn't the latest for your board it may be worth updating. Make sure you restore factory defaults before updating to ensure a smooth update without any issues. I am afraid that's about all I can offer advice wise, this secure boot nonsense is something I just disable. It causes nothing but issues. Might be something to do with the fact that you upgraded from Windows 10, I find upgrading is always problematic unless it was an upgrade from a fresh install of the previous OS. Even then there can be issues. Maybe one of our other forum members knows a bit more on the subject. I am more on the hardware side of things these days. -------------
