Hello everyone, I checked whether my PC could support secure boot for Windows 11. I opened the BIOS and attempted to turn it on, but it asked me to be in a specific user mode and provided a platform key. I saved the settings and restarted the computer—still no booting even after entering BIOS. The system powers on, fans spin, but no image appears and the monitor doesn’t detect anything. My hardware details are: MSI B450 S2H Rysen 1600 VIPER 16 GB 3200 Hz SAPPHIRE NITRO+ Radeon RX 580 1 TB SSD 2 TB HDD. I tried resetting the CMOS by removing the BIOS battery for 15 minutes, but it didn’t work. I also unplugged both the SSD and HDD to see if the BIOS would appear, but that didn’t happen either.
