I turned on secure boot in BIOS and updated the keys. Made sure the boot drive was set to GPT. The PC won’t start. I reset the CMOS to reconnect to BIOS. BIOS reported an invalid signature and said to block the ROM execution. It won’t boot, and I can’t get BIOS to start either. I’ve removed drives and tried booting, but nothing appears on screen. Usually, after changing BIOS settings and facing boot problems, the GPU light stays off. Once CMOS was reset and I restarted several times, the GPU turned on, but even after resetting and rebooting, I still see nothing.

It’s not possible to just turn on the feature and start using the system right away. For optimal security, install Windows with Secure Boot enabled. If you must proceed, make sure to save any important information and reinstall from a clean disk.

3090, Asrock b650e itx, 7500f. It seems mb doesn’t support integrated graphics and lacks BIOS flash support. I attempted to use an old Radeon 7850 that was available, but it didn’t work. The chat gpt suggests it won’t function with AM5 chips. The only viable path appears to be obtaining an SPI programmer, which feels quite challenging for a home setup. I’m really unsure about my next steps.

The update to secure boot keys was likely unsuccessful. Many HD 7XXX cards lack UEFI GOP, so I had to modify one into my HD7850. The message "Secure boot invalid signature detected" suggests the key update didn't succeed or you're using an unsigned bootloader, indicating your installation wasn't done in UEFI mode.
