Failed to reach BIOS following Windows 11 installation.
Failed to reach BIOS following Windows 11 installation.
After delaying for months, I finally switched to Windows 11. My equipment is somewhat outdated, so I had to adjust the BIOS settings to fit the specs. Here’s what I have: my current gear, the BIOS modifications, and the troubleshooting steps I’ve tried. Hardware includes an Asus Prime X470-Pro board with a Ryzen 7 3700X, a Corsair Vengeance LPX 3000mhz, a 32 GB NVMe drive, a WD Black M.2 500 GB, and a WD Blue 3.5 TB. BIOS changes involved: updating to the latest version, turning off CSM, enabling Secure Boot (changing to UEFI only), activating fTPM. Initially I could update but later lost access—no splash screen, no BIOS entry, and even Advanced Recovery led to a blank screen requiring a restart. I searched online and found a forum tip about a command to force a BIOS restart, though it only reset the system. Clearing CMOS restored access, then I reverted settings, disabled Fast Boot, and adjusted POST delay from 3 to 5 seconds. Still no success. Further research revealed the BIOS was in beta; I downloaded the stable version, reset CMOS again, and flashed it back. This time I overclocked RAM to 3200mhz and cleared it, but the issue persisted. Eventually, I followed AI advice: disabling CSM removed legacy support for older GPU firmware, prompting a Nvidia firmware update. Running the scan tool fixed the problem—my display firmware matched the required version. Now I can boot into BIOS without black screens. For those facing similar issues, the Nvidia update resolved it. If you’re stuck, try the same steps but ensure your GPU is up to date and consider a fresh BIOS install.

I frequently use it, just without the /f option that automatically closes anything I haven’t closed before. It usually works fine on its own. Just need a single zero to skip waiting. If it fails, it might point to an issue with your system, though I’m not sure of the exact cause.
Thank you for reading the article. Unfortunately, the problem didn't resolve as expected. I've reached out to Asus customer support, who also seemed puzzled by the issue. They've taken notes and plan to investigate further, reaching out to me in a few days. I'm hoping they'll provide a solution soon!
Ensure your keyboard is configured to permit the PC from a sleep mode. This helps the system respond quickly when you press the delete key after rebooting. If the setting isn't active, the PC might lag in recognizing commands. It can also be necessary to adjust a BIOS option so the machine wakes up using mouse or keyboard input.
I verified the keyboard can wake the PC from sleep mode. Next, I need to review the USB power configuration in the BIOS after resetting the CMOS, and then restore the RAM speed to its original factory settings (refer to the post edit).
