Secure boot ensures that only digitally signed operating systems run on your Surface device. Secure boot helps protect against bootkits, or malware that infects the master boot record (MBR) on your computer. While there should be no need to change this setting, if you plan on installing an older operating system such as Windows 7 and earlier or run operating systems that are unsigned such as some distributions of Linux, you may need to disable secure boot to be able to run these needed operating systems. This wikiHow will show you how to disable secure boot so you can boot a legacy operating system or an OS that does not support secure boot. [1]

    Did you or your organization set a firmware password? If so, then you will need to enter it to change firmware settings. Note that you cannot recover your firmware password if you lose it, so keep it safe. (There is probably software that can crack the firmware password of any computer.)
