Windows 11 & PC Maintenance Scan - No UEFI firmware ROM detected -> CSM activated -> Secure Boot disabled
Windows 11 & PC Maintenance Scan - No UEFI firmware ROM detected -> CSM activated -> Secure Boot disabled
Hello, I'm asking about the expert opinions. PC Health Check confirms everything is fine for installing Windows 11 and mentions Secure Boot support. However, it's currently turned off, which is necessary because my old graphics card (GTX 670) lacks UEFI OpROM. To proceed, I need to enable Secure Boot via CSM. My concern is whether the upgrade will fail if Secure Boot remains disabled after installation, especially since the graphics card is the root cause. While replacing the card would be straightforward, it's not currently a simple option. Thank you ahead for your help!
The PC allows secure boot, but also lets it be turned off. So, the best approach would be to turn it on, set up W11, and then disable it again. Or, you could attempt to install W11 without enabling secure boot first. You won't have to worry much. In the worst scenario, the installation might fail and you'll have your answer. As far as I understand, W10 should create a system image before an upgrade, so if it doesn't install properly, it should revert to the previous state. Let me know if that's correct.
Thank you for your feedback. It seems enabling Secure Boot is causing issues because my graphics card isn't recognized as UEFI compatible. Since it's a PCIe device, I'm unable to use Secure Boot. Removing it stopped the display, so I can't install anything. I'll try installing without Secure Boot and see how it goes. Appreciate your understanding!
Ensure your GPU has the latest vBIOS update for UEFI support. Once activated, it will only function properly in UEFI mode—rolling back isn’t possible. Consult the manufacturer for details. Ideally, this should have been done during warranty coverage, allowing replacement if the update fails and the card becomes unusable. However, it seems a bit too late now, and timing might not be ideal.
