Activate Secure Boot configuration.
Activate Secure Boot configuration.
Hello Everyone, I'm working on getting ready for Windows 11 and need to enable Secure Boot in the BIOS. I already have TPM 2.0 enabled via BIOS and my system runs UEFI. My GPU supports UEFI too, but after trying to activate Secure Boot I encountered issues. I disabled CSM Support, selected the Secure Boot option, set a Platform Key (default), and saved the changes. After exiting, the PC entered a boot loop, showing a sequence like GPU → CPU → RAM → Boot, but then it would restart repeatedly. The screen would go blank after enabling Secure Boot, and I noticed the board has four diagnostic LEDs. It normally boots in a standard POST order (GPU → CPU → RAM → Boot) and shows the Windows logo. After clearing the CMOS by removing the battery, the system restarted successfully. Now I'm wondering if there are any BIOS settings I should adjust before trying Secure Boot again. My current details: Motherboard – Gigabyte x470 Ultra Gaming (rev 1); BIOS – F6; Processor – Ryzen 5 2600; RAM – 16GB Corsair (8x2 @ 3GHz); GPU – MSI GeForce GTX 1060 6GB (OC V2). Thanks, Souvik.
After turning on Secure Boot, you might need to reinstall Windows. This could cause GPU issues during POST since the system can't locate the boot drive. Windows 11 appears more complicated now. I'm worried about applying Secure Boot on my Gigabyte board using an older F5 BIOS version.
Prior to this, you might want to check if enabling CSM in auto mode is feasible. Please let me know the outcome of your experience.
Well then, the issue is unclear. You didn’t mention any legacy devices or accessories, so why would CSM be activated? Unless you really need something unusual—like using hardware that doesn’t support UEFIs—CSM should never be turned on.
I hadn't checked that BIOS setting before looking for the secure boot option because of the Windows 11 requirements. I believe it was turned on by default. It's possible to disable it without any problems. However, my main issue is with the Secure Boot activation—my system entered an infinite loop. I'm trying to resolve or understand why this happens. It looks like my hardware supports secure boot, but it seems to trigger that loop. Could it be related to having Windows 10 installed? I converted the boot drive from MBR to GPT before trying secure boot. Now I have two additional storage drives in MBR, and I'm wondering if they might be causing this behavior.
