Many PC manufacturers utilize a “Secure Boot” feature on newer Windows 8 PCs that use the UEFI or EFI boot standard, which prevents computers and laptops from booting from external media such as bootable USB sticks, CDs, and DVDs. This guide will show you how to disable “Secure Boot” on your PC, allowing you to boot into recovery discs and setup CDs for operating systems other than Windows, such as Linux or previous versions of Windows. Depending on your system settings, you may also need to set up your UEFI “BIOS” to enable legacy mode.

Turning off Secure Boot on most PCs and laptops, as well as specific steps for specific laptop brands, is detailed below. On most EFI machines, you’ll need to go to EFI setup right after turning it on to see the option to turn off Secure Boot, which is normally found under the boot options part of the BIOS menu.

Entering the UEFI configuration

You will have the option of hitting a specific key when the manufacturer logo (e.g., Dell, Lenovo, HP, Toshiba, Samsung, ASUS, Acer, Gateway, etc.) appears on your BIOS splash screen after powering up your PC. This key varies from PC to PC, depending on the make and model of your computer.

The key will usually be indicated by a small notification at the bottom or top of the screen. The legend in the top-right corner of one such screen indicates that pressing F2 will start the BIOS setup, and pressing F12 will reveal the boot selection menu.

The F2, F8, F12, and Del keys are typical alternatives. It may, however, be any of the other hundred keys on your keyboard.

The specific procedures will vary depending on the make and model of your PC, but generally, navigating with the and arrow keys will bring you to the options of “discard changes and exit” vs. “save changes and exit,” among others. You must select the “save changes and quit” option. Although the keyboard shortcut F10 frequently means “save and exit,” you should double-check before using it.
