It is intended to replace MS-DOS boot disks and can be booted via USB flash drive, PXE, iPXE, [1] CD, DVD, or hard drive. Traditionally used by large corporations and OEMs (to preinstall Windows client operating systems on PCs during manufacturing), it is now widely available free of charge via Windows Assessment and Deployment Kit (WADK ...
Multiboot is environmental technology since it requires only a single storage device to boot multiple files. "Persistence" is the ability, for a Linux Live distribution, to save the changes (to e.g. software, documents, parameters, etc) in the live USB across reboots.
A type of UEFI application is an OS boot loader such as GRUB, rEFInd, Gummiboot, and Windows Boot Manager, which loads some OS files into memory and executes them. Also, an OS boot loader can provide a user interface to allow the selection of another UEFI application to run. Utilities like the UEFI Shell are also UEFI applications.

A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

The bootable virtual floppy disk can contain software that provides access to the optical medium in its native format. If an expansion ROM wishes to change the way the system boots (such as from a network device or a SCSI adapter) in a cooperative way, it can use the BIOS Boot Specification (BBS) API to register its ability to do so. Once the ...
Universal USB Installer (UUI) is an open-source live Linux USB flash drive creation software. It allows users to create a bootable live USB flash drive using an ISO image from a supported Linux distribution, antivirus utility, system tool, or Microsoft Windows installer. The USB boot software can also be used to make Windows 8, 10, or 11 run ...
GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
