REFIt

rEFIt is a boot menu and maintenance toolkit for EFI-based machines like the Intel Macs. It can be used to boot multiple operating systems, including triple-boot setups with software such as Apple's Boot Camp Assistant. It also provides a way to enter and explore the EFI pre-boot environment.^[6] The name "rEFIt" is likely a play on the terms "refit" and "EFI".
