To enable Secure Boot on MSI Click BIOS 5, you need to make sure the system is running in pure UEFI mode, disable CSM/Legacy support, then turn on Secure Boot and load the factory keys so the system switches from Setup Mode to User Mode.

Before you start

  • Secure Boot only works in UEFI mode; it does not work with Legacy/CSM boot.
  • Windows should be installed in UEFI mode (drive usually formatted as GPT, not MBR), otherwise the system may fail to boot after you enable Secure Boot.
  • If you see messages like “System in Setup Mode. Secure Boot can be enabled when system in User Mode,” it just means the Secure Boot keys are not loaded yet and needs a quick fix in BIOS.

Step 1: Enter MSI Click BIOS 5

  1. Restart your PC.
  2. While the MSI logo shows, press Delete repeatedly until Click BIOS 5 opens.
  1. If you see the simplified EZ Mode , press F7 to switch to Advanced Mode.

Step 2: Force UEFI boot and disable CSM

  1. Go to:
    • Settings → Advanced → Windows OS Configuration.
  1. Find Boot Mode Select and set it to UEFI (not “Legacy+UEFI” and not “Legacy”).
  1. Then go to:
    • Settings → Advanced → CSM/Legacy Support (wording can vary slightly by board).
  1. Set CSM (or Legacy Support) to Disabled so only UEFI boot is allowed.

If Windows was originally installed in Legacy/MBR mode, switching to UEFI and disabling CSM can cause it not to boot; in that case you must either reinstall Windows in UEFI mode or convert the disk with tools such as MBR2GPT before doing these steps.

Step 3: Open Secure Boot menu

  1. In Advanced Mode, go to:
    • Settings → Advanced → Secure Boot.
  1. Here you’ll see options like Secure Boot , Secure Boot Mode , and a status line such as System Mode: Setup/User depending on your board and BIOS version.

If the Secure Boot option is greyed out, that almost always means either CSM is still enabled or the system is not in pure UEFI mode; double‑check Step 2.

Step 4: Load factory keys and switch to User Mode

Many MSI boards ship with Secure Boot in Setup Mode , which blocks enabling it until the keys are loaded.

Do the following:

  1. In Settings → Advanced → Secure Boot , set Secure Boot Mode to Standard (not Custom).
  1. If it is already on Standard but you still see Setup Mode, flip it to Custom , then back to Standard ; you will usually be prompted to “Load factory default keys” or similar.
  1. Accept/confirm loading the default keys.
  2. After this, the Secure Boot status should change to User Mode , which means you can now enable Secure Boot.

This “flip to Custom then back to Standard to load keys” trick is exactly what many guides and videos recommend when Secure Boot refuses to enable on MSI Click BIOS 5.

Step 5: Enable Secure Boot

  1. Still in the Secure Boot menu, set Secure Boot to Enabled.
  1. Leave Secure Boot Mode on Standard unless you have a special need to manage keys manually; Standard uses MSI’s default manufacturer keys and is fine for Windows 10/11 and most signed Linux distros.

Then:

  1. Press F10 to Save & Exit, confirm, and let the system reboot.

If the PC suddenly stops booting into Windows after this, it usually means Windows was installed in Legacy mode and is not compatible with Secure Boot until you reinstall/convert to UEFI as mentioned earlier.

Step 6: Confirm Secure Boot inside Windows

Once you are back in Windows:

  1. Press Windows + R , type msinfo32, and press Enter.
  1. In System Summary , look for Secure Boot State.
    • If it shows On , then Secure Boot is successfully enabled.
    • If it shows Off or Unsupported , something in BIOS is still misconfigured (often CSM still enabled or OS not installed in UEFI).

Common problems and quick fixes

  • Secure Boot option greyed out
    • Make sure:
      • Boot Mode is set to UEFI only.
  * **CSM/Legacy** is fully disabled.

  * Secure Boot Mode is **Standard** , with factory keys loaded.
  • Message: “System in Setup Mode. Secure Boot can be enabled when system in User Mode”
    • In the Secure Boot menu, toggle between Standard and Custom, then choose to load factory default keys.
* After keys are loaded, System Mode should become **User** and the Secure Boot toggle will become available.
  • PC boots only to BIOS or black screen after enabling Secure Boot
    • Likely Windows is on an MBR disk installed in Legacy mode. You must either reinstall Windows in UEFI with a GPT disk or convert using a tool like MBR2GPT first.

Quick SEO-style meta note

Enabling Secure Boot on MSI Click BIOS 5 is important both for Windows 11 requirements and for blocking low‑level malware at boot, and forum discussions plus recent how‑to guides show this remains a common 2025–2026 “trending” setup task for PC builders and gamers upgrading older systems.
