Problems related to starting secure boot
To run FIFA 23 on my PC, I need to adjust the secure boot settings in my BIOS. After installing Windows 8.1 or 10, I switched the secure boot mode to custom and imported all default keys. A warning appeared advising me to turn off CSM during setup and reboot. Once I restarted, the system didn’t start properly and required a CMOS reset. My motherboard is an older model, and I’m unsure about the exact steps to disable CSM in the setup process. I think my GPU supports UEFI, but there’s confusion about converting from MBR to GPT. The warning now clearly states: “Warning: CSM is loaded! Disable the CSM in setup. Repeat operation after reboot to ensure UEFI Video (GOP) driver is operational.” My hardware details are noted, and I’m trying to figure out how to fix this issue.
CSM controls whether legacy BIOS functionality is activated on UEFI systems. The method to disable it varies by hardware, but generally you aim for UEFI-only mode instead of legacy settings, which aligns with the forum suggestion. Keep in mind that if Windows is configured for legacy boot and CSM/legacy boot is turned off, Windows will likely fail to start. While technically possible to modify an installation, it requires significant expertise with UEFI, Windows boot sequences, and tools like diskpart, bcdboot, and bcdedit.
Thank you for your reply and details. It turned out a simpler fix worked. I could simply switch back to Windows 10 instead of 11, which resolved the game problem. Even when set to UEFI mode, my PC wouldn’t boot after turning off CSM. It might be a compatibility issue or something I didn’t do correctly. Still, any workaround that avoids messing with the boot process seems best, especially since I’m not familiar with it.
