PCs that come with Windows 8 and Windows 8.1 include UEFI firmware instead of the traditional BIOS. By default, the machine’s UEFI firmware will only boot boot loaders signed by a key embedded in the UEFI firmware. This feature is known as “Secure Boot” or “Trusted Boot.”
Secure Boot
On traditional PCs without this security feature, a rootkit could install itself and become the boot loader. The computer’s BIOS would then load the rootkit at boot time, which would boot and load Windows, hiding itself from the operating system and embedding itself at a deep level. So the computer with secure boot will only boot trusted software, so malicious boot loaders won’t be able to infect the system.
How to Disable Secure Boot
You can control Secure Boot from your UEFI Firmware Settings screen. To access this screen, you’ll need to access the boot options menu in Windows 8. To do this, open the Settings charm — press Windows Key + I to open it — click the Power button, then press and hold the Shift key as you click Restart.
Your computer will restart into the advanced boot options screen. Select the Troubleshoot option, select Advanced options, and then select UEFI Settings. (You may not see the UEFI Settings option on a few Windows 8 PCs, even if they come with UEFI — consult your manufacturer’s documentation for information on getting to its UEFI settings screen in this case.)
You’ll be taken to the UEFI Settings screen, where you can choose to disable Secure Boot or add your own key.
Boot From Removable Media
You can boot from removable media by accessing the boot options menu in the same way — hold Shift while you click the Restart option. Insert your boot device of choice, select Use a device, and select the device you want to boot from.
After booting from the removable device, you can install Linux as you normally would or just use the live environment from the removable device without installing it.
