EFI file is stored on the hard drive on a special partition called EFI System Partition (ESP). UEFI provides a faster boot time. UEFI has discrete driver support, while BIOS has disk support stored in the ROM, so updating BIOS firmware is difficult.
Which is better, EFI or BIOS?
Compared to BIOS, UEFI is more powerful and has more advanced features. It is the latest method of booting a computer, designed to replace the BIOS. BIOS uses the Master Boot Record (MBR) to store information about the data on the hard drive, while UEFI uses the GUID Partition Table (GPT).
What does EFI mean in BIOS?
The Extensible Firmware Interface (EFI) system partition or ESP is a partition on a data storage device (usually a hard drive or solid-state drive) used by computers that adhere to the Unified Extensible Firmware Interface (UEFI).
What are UEFI and BIOS used for?

Should I boot from UEFI or Legacy?
Compared to Legacy, UEFI has better programmability, greater scalability, higher performance, and higher security. UEFI provides a secure boot to avoid loading several on the boot. Windows system supports UEFI from Windows 7, and Windows 8 uses UEFI by default.
Can UEFI MBR boot?
WhBootUEFI supports the traditional boot (Master Boot Record) method of partitioning hard drives; it doesn’t stop there. It can also work with the GUID Partition Table (GPT), free from the MBR’s restrictions on the number and size of partitions. UEFI may be faster than BIOS.
What does EFI do?
