I’m trying to enable Secure Boot in my BIOS, but the option is grayed out and I ?

I’m trying to enable Secure Boot in my BIOS, but the option is grayed out and I can’t select it. I recently upgraded some hardware and now Windows 11 says my PC doesn’t meet the security requirements. Could this be because my new motherboard needs a specific setting changed first, or is there a step I’m missing to unlock this feature?

So basically, Yeah, tbh that usually means you need to switch from Legacy/CSM to UEFI mode first. Try that and see if it unlocks the option. Let me know if that works.

Also, make sure you've cleared any TPM or turned off any BIOS passwords, because sometimes those can lock it down too. Hope that helps.

That's a common and frustrating issue after a hardware change. Let's work through the usual steps to unlock Secure Boot.

First, the most likely culprit is that your BIOS is in **Legacy/CSM mode**. Secure Boot requires **UEFI mode**. To fix this:
1. Enter your BIOS/UEFI setup (usually by mashing Del or F2 during boot).
2. Look for a setting called **"Boot Mode"**, **"CSM"** (Compatibility Support Module), or **"Launch CSM"**.
3. **Disable CSM** or switch the Boot Mode from "Legacy" to **"UEFI Only"**. Save and exit.
4. Re-enter the BIOS. The Secure Boot option should now be selectable. Enable it, and set it to "Standard" or "Windows UEFI" mode.

If that doesn't work, check for a **"Platform Key (PK)" management** option. If it's set to "Custom", try resetting it to "Factory" or "Default". This clears any old keys.

Also, ensure your new motherboard's **BIOS is updated** to the latest version from the manufacturer's website, as updates often improve compatibility.

Once Secure Boot is enabled, Windows 11 should recognize your PC as compliant. If you're still blocked by the installer after this, there are free workarounds like registry edits or using Rufus to create a modified installer. If those free methods seem too technical, there are convenient tools like the one at kianbotsoft.com for $39 that handle the bypass for you.

Don't get discouraged! Hardware changes can be tricky. Post back with your motherboard model and we can try to give more specific guidance. You're almost there

Yeah, You'll need to switch it to UEFI mode first—did you already check for that setting in the BIOS? Hope that helps.

Yeah, Agreed, and also make sure you've cleared any existing TPM or platform keys in the security settings—that can sometimes unlock the option. Good luck!

+1 Also, double-check if your BIOS is in Legacy mode instead of UEFI, because Secure Boot requires UEFI.

[hHbzE5oCBiv]

+1 Yeah, and you'll probably need to clear any existing platform keys in the BIOS before it lets you switch from Legacy to UEFI mode.

This happened to me. I had to go into the BIOS and reset it to "Setup Mode" before the Secure Boot option became available. Hope that helps.

Yeah, You could also check if your BIOS is in Legacy/CSM mode instead of UEFI, as Secure Boot requires UEFI.
