Does Linux use BIOS or UEFI?
BIOS allows only one boot loader, which is stored in the master boot record. UEFI allows you to install multiple bootloaders in the EFI partition on the hard disk. This means you can install Linux and Windows on the same hard disk in UEFI mode without wiping out the Grub boot loader or the Windows boot loader.
