This guide covers some of the common ways to disable &#8220;Secure Boot&#8221; on your PC, letting you boot into recovery media and setup CDs for other operating systems like Linux or older versions of Windows. Depending on your system configuration, you may also need to set up your <a href=\"https:\/\/neosmart.net\/wiki\/enable-legacy-boot-mode\/\">UEFI &#8220;BIOS&#8221; to enable legacy mode<\/a>.<\/p>\n<h2>Secure Boot<\/h2>\n<p>Originally designed as a security measure, Secure Boot is a feature of many newer EFI or UEFI machines (most common with Windows 8 PCs and laptops), which locks down the computer and prevents it from booting into anything but Windows 8. It is often necessary to disable Secure Boot to take full advantage of your PC.<\/p>\n<h3>Reasons to disable Secure Boot<\/h3>\n<p>There are several reasons why it might be necessary to disable Secure Boot on your workstation or laptop, that include<\/p>\n<ul>\n<li>Installing an older version of Windows<\/li>\n<li>Installing Linux, BSD, or another operating system<\/li>\n<li>Running system repair CDs or utilities (such as NeoSmart Technologies&#8217; <a href=\"http:\/\/neosmart.net\/EasyRE\/\">Easy Recovery Essentials for Windows<\/a>)<\/li>\n<li>Performing advanced PC maintenance procedures, such as BIOS or firmware updates<\/li>\n<\/ul>\n<h2>Disabling Secure Boot<\/h2>\n<p>On PCs and laptops from most manufacturers, including Dell, HP, Asus, Acer, Toshiba, Lenovo, and more, Secure Boot can be disabled from the EFI setup\/configuration feature, available immediately after turning on your PC. While some makes and models of laptops actually do not let you turn off Secure Boot, the following instructions should work for most users.<\/p>\n<p>Below are instructions for turning off\u00a0Secure Boot on most PCs and laptops, as well as specific instructions for certain brands of laptops. On most EFI computers, you&#8217;ll need to access EFI setup immediately after turning on your PC in order to see the option of switching\u00a0off Secure Boot, usually as an option under the boot options section of the BIOS configuration.<\/p>\n<h4>Entering the UEFI setup<\/h4>\n<div id=\"attachment_1419\" style=\"width: 310px\" class=\"wp-caption alignright\"><a href=\"\/wiki\/wp-content\/uploads\/sites\/5\/2013\/09\/Dell-POST.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1419\" class=\"size-medium wp-image-1419  colorbox-2048\" src=\"\/wiki\/wp-content\/uploads\/sites\/5\/2013\/09\/Dell-POST-300x224.jpg\" alt=\"Dell BIOS screen showing special key options\" width=\"300\" height=\"224\" srcset=\"https:\/\/i0.wp.com\/neosmart.net\/wiki\/wp-content\/uploads\/sites\/5\/2013\/09\/Dell-POST.jpg?resize=300%2C224&amp;ssl=1 300w, https:\/\/i0.wp.com\/neosmart.net\/wiki\/wp-content\/uploads\/sites\/5\/2013\/09\/Dell-POST.jpg?resize=60%2C44&amp;ssl=1 60w, https:\/\/i0.wp.com\/neosmart.net\/wiki\/wp-content\/uploads\/sites\/5\/2013\/09\/Dell-POST.jpg?resize=150%2C112&amp;ssl=1 150w, https:\/\/i0.wp.com\/neosmart.net\/wiki\/wp-content\/uploads\/sites\/5\/2013\/09\/Dell-POST.jpg?w=450&amp;ssl=1 450w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p id=\"caption-attachment-1419\" class=\"wp-caption-text\">Notice the key guide in the top-right corner.<\/p>\n<\/div>\n<p>Immediately after powering up your PC, as soon as the manufacturer logo (e.g. Dell, Lenovo, HP, Toshiba, Samsung, ASUS, Acer, Gateway, etc.) shows up on your BIOS splash screen, you will have the option of pressing a special key.\u00a0<strong>This key changes from PC to PC<\/strong>, it all depends on your PC&#8217;s make and model.<\/p>\n<p>Typically, you will see a brief note at the bottom or top of the screen indicating what the key is.\u00a0One such screen is visible to the right, note the legend in the top-right corner indicating\u00a0<kbd>F2<\/kbd>\u00a0will start the BIOS setup and\u00a0<kbd>F12<\/kbd>\u00a0will present the boot selection menu.<\/p>\n<p>Some common options include the\u00a0<kbd>F2<\/kbd>,\u00a0<kbd>F8<\/kbd>,\u00a0<kbd>F12<\/kbd>, and\u00a0<kbd>Del<\/kbd>\u00a0keys.\u00a0However, it could be any of the one hundred other keys on your keyboard.<\/p>\n<h4>Switching off Secure Boot<\/h4>\n<p>Once inside the UEFI setup and configuration section, you&#8217;ll be presented with a number of options and parameters that can be configured for the firmware environment.
