| 2020.12.09 | How to | No Comments

Disabling Secure Boot would be required for example in order to enable Test Mode for Windows if you received the “The value is protected by Secure Boot policy” error, in some cases if you want to install a specific Linux OS or if you want to install Windows 7. The exact location and procedure to enable or disable Secure Boot can vary depending on the BIOS version and motherboard generation.

Generic instructions

Disable Secure Boot
  1. Enter the BIOS:
    1. Reboot system and press Del repeatedly at system start. Some OEM PC(HP, Dell, Acer, Lenovo, Toshiba etc.) and notebooks use keys like F1, F2, F8, F10, or F12 for entering BIOS.
    2. If that does not work, go in Windows, hold the “Shift” key, and select Restart from the Start Menu. After restart, the Advanced Startup menu options will appear. Go to Troubleshoot > Advanced options > UEFI Firmware Settings and press Restart.
  2. Look for the “Secure Boot” option under the Boot, Security, or Authentication menu categories.
