To enable Secure Boot on an MSI motherboard, follow these key steps:
- Enter BIOS Setup by restarting the PC and pressing the DEL key during boot.
- Switch the BIOS to Advanced Mode (usually by pressing F7).
- Navigate to the Settings menu, then go to Advanced > Windows OS Configuration.
- Set the BIOS to UEFI mode by enabling Windows 10 WHQL support; disable CSM (Compatibility Support Module).
- Go to the Security menu, then Secure Boot.
- Set Secure Boot Mode to Custom and enable Secure Boot.
- If switching from legacy BIOS or CSM mode, save changes and restart the PC, then re-enter BIOS to enable Secure Boot fully.
- Save changes and exit BIOS.
Make sure the boot drive is formatted with GPT and the system boots in UEFI mode, as Secure Boot only works with UEFI and GPT partition style. If the system drive is in MBR format, it needs converting to GPT before enabling Secure Boot to avoid data loss. Additional steps:
- In Secure Boot settings, you may also need to enroll factory default keys if prompted.
- Updating BIOS to the latest version may be necessary to support Secure Boot fully.
This process can vary slightly with different MSI BIOS versions, but the general flow is consistent.
