Experience a nightmare involving CSM and Secure Boot configurations.
Experience a nightmare involving CSM and Secure Boot configurations.
The relevant hardware includes an i7-9700k CPU, a 980TI MB ASROCK Z390 Phantom Gaming 4S-IB graphics card. First, I completed the mbr2gpt process, though it didn't work in Windows PE or the full operating system version. Eventually, I spent about three hours on EaseUS, which finally converted my drive to GPT format—success! That step is complete and the drive appears correctly. Next, I attempted to disable CSM in the BIOS, but it wouldn't post. I unplugged one monitor and managed to get it to boot, which was encouraging. However, now none of my boot drives are showing up. To try a fix, I updated my BIOS (a challenge since my motherboard model wasn't listed on ASROCK's site—I had to dig through iBuyPower’s content). The BIOS update worked, but the issue persists. I checked in GPU-Z to confirm UEFI is enabled for my GPU, and it is. Still, I don’t have any online guides that explain how to resolve this, as most people seem to have already fixed it early on. Any advice or suggestions would be invaluable!

06-26-2021, 01:09 PM #1I've been working through all the procedures to activate secure boot and move to Windows 11. It feels like I've checked countless online resources, but each suggestion seems to hit a roadblock on my system (which is honestly a basic configuration). I'm starting to feel discouraged because I really want to upgrade but am hesitant to wait until my next build.

06-26-2021, 09:30 PM #2I believe the issue likely stems from the drives not being properly configured as GPT. It might help to verify their partition layout—specifically checking for a data partition and a dedicated boot partition. The problem with CSM and TPM settings seems unrelated, but workarounds exist, such as performing a clean installation, which is generally advisable due to potential instability from the current setup.

To ensure your drive uses the GPT partition setup during a clean install, verify your current partition layout and consider backing up important data. Research the installation process for Windows 11 requirements, especially regarding partitioning, and follow official guides to avoid compatibility issues later.
