Understanding Legacy Boot
Legacy boot, also known as BIOS (Basic Input/Output System) boot, is a boot method that allows older operating systems and devices, such as Windows XP or external USB drives, to boot on newer computers. Unlike UEFI boot, legacy boot does not require the use of UEFI-compatible devices or operating systems.
