UEFI firmware supports booting from removable storage devices such as USB flash drives. For that purpose, a removable device is formatted with a FAT12, FAT16 or FAT32 file system, while a boot loader needs to be stored according to the standard ESP file hierarchy, or by providing a complete path of a boot loader to the system's boot manager. On ...
OS boot loaders can be automatically detected by UEFI, which enables easy booting from removable devices such as USB flash drives. This automated detection relies on standardized file paths to the OS boot loader, with the path varying depending on the computer architecture .

Examples of removable media that are standalone plug-and-play devices that carry their own reader hardwares include: USB flash drives [5] Portable storage devices. Dedicated external solid-state drives (SSD) Enclosured mass storage drives, i.e. modified hard disk drives (HDD)/internal SSDs; Peripheral devices that have integrated data storage ...
The GUID Partition Table is specified in chapter 5 of the UEFI 2.11 specification. [ 2 ] : 111 GPT uses 64 bits for logical block addresses, allowing a maximum disk size of 2 64 sectors. For disks with 512‑byte sectors, the maximum size is 8 ZiB (2 64 × 512‑bytes) or 9.44 ZB (9.44 × 10²¹ bytes). [ 1 ]
A volume boot record (VBR) is the first sector of a data storage device that has not been partitioned, or the first sector of an individual partition on a data storage device that has been partitioned. It may contain code to load an operating system (or other standalone program) installed on that device or within that partition.
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc, and usually weighs less than 30 g (1 oz).
A modern PC's UEFI or BIOS firmware supports booting from various devices, typically a local solid-state drive or hard disk drive via the GPT or Master Boot Record (MBR) on such a drive or disk, an optical disc drive (using El Torito), a USB mass storage device (USB flash drive, memory card reader, USB hard disk drive, USB optical disc drive ...
