UEFI:: :: A newer system to replace BIOS. UEFI stands for Unified Extensible Firmware Interface, often called just EFI for short (for historical reasons). It includes a hardware-based security measure to help protect against malware. = EFI and this process = These instructions pertain to machines with EFI. If your computer is too old to have EFI, or for some reason you have disabled it, you would need a modified process, and the Boot cannot be encrypted. See [[../#Advanced_features|Advanced features]]. = Do I have EFI? = == Windows == Press `Win`+`R` and enter `msinfo32`. In the window that opens, in the right-hand column, look for "BIOS Mode". * If it says "Legacy", your computer doesn't use EFI and this process won't work. * If it says "UEFI", your computer uses EFI and you can use this process. == Linux == 1. Open a terminal (`Ctrl`+`T`). 1. Type (or cut-and-paste) the following command. {{{ [[ -e /sys/firmware/efi ]] && echo EFI || echo BIOS }}} * If the result reads "BIOS", your computer doesn't use EFI and this process won't work. * If the result reads "EFI", your computer uses EFI and you can use this process. ---- CategoryInstallation CategorySecurity
