difference uefi and legacy boot
The difference between UEFI Boot and Legacy boot is the process that the firmware uses to find the boot target. Legacy Boot is the boot process used by BIOS firmware. The firmware maintains a list of installed storage devices that may be bootable (Floppy Disk Drives, Hard Disk Drives, Optical Disk Drives, Tape Drives, etc...) and enumerates them in a configurable order of priority.
Hi, Below are the difference between UEFI and Legacy: Unified Extensible Firmware Interface(UEFI) is the successor to BIOS. UEFI uses the GUID Partition Table (GPT) whereas BIOS uses the Master Boot Record(MBR) partitioning scheme. GPT and MBR are both formats specifying physical partitioning information on the hard disk. Below I have listed the difference: Max partition size in MBR is ~2TB whereas in UEFI it is ~9 ZetaBytes
