Rufus was originally designed [5] as a modern open source replacement for the HP USB Disk Storage Format Tool for Windows, [6] which was primarily used to create DOS bootable USB flash drives. The first official release of Rufus, version 1.0.3 (earlier versions were internal/alpha only [ 7 ] ), was released on December 4, 2011, with originally ...
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.
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 ...
Live USB OSes like Ubuntu Linux apply all filesystem writes to a casper filesystem overlay (casper-rw) that, once full or out of flash drive space, becomes unusable and the OS ceases to boot. [citation needed] USB controllers on add-in cards (e.g. ISA, PCI, and PCI-E) are almost never capable of being booted from, so systems that do not have ...
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
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.

On Apple Mac computers using Intel x86-64 processor architecture, the EFI system partition is initially left blank and unused for booting into macOS. [13] [14]However, the EFI system partition is used as a staging area for firmware updates [15] and for the Microsoft Windows bootloader for Mac computers configured to boot into a Windows partition using Boot Camp.
Drawbacks are that some older devices may not support USB booting and that the USB storage devices lifespan might be shortened. Ubuntu has included a utility for installing an operating system image file to a USB flash drive since version 9.10. [1] Windows support also has added a step by step on how to set up a USB device as a bootable drive. [2]
