PC Specifications
Mobo: ASRock X570 Pro4
CPU: Ryzen 5 2600
GPU: RX 580 4GB
RAM: 16GB
SSD: Team Group 256GB
My problem is that after updating the BIOS from version 4.20 to 4.26 and once the update is done, my PC refuses to start up.
I attempted to reset the CMOS but it didn’t change the outcome; the PC still won’t boot.

Navigate through the bios and ensure your configurations match the previous settings prior to the update. I’m experiencing a problem with an older system where the OS resets, affecting the secure boot configuration. After reverting it to its original state, the boot process works correctly again.
