They are pieces of software that is embedded on some chip or controller on the hardware, i.e. the motherboard of a server. Both BIOS and UEFI look for instructions on the disks that help locate the respective bootloader. BIOS Looks for the MBR (Master Boot Record) in the first sector of the disk. UEFI looks for the <em>.efi</em> files that are located in the EFI Special Partition (ESP) under <em>/boot/efi/EFI/</em>. Once the bootloader is located, the interface (BIOS or UEFI) loads it in memory and give it control for the rest of the OS boot operations.</p>
