The '''GRUB''' is used to manage and boot up linux operating systems on computers that do not have UEFI, or at least have UEFI disabled (also known as running in '''Legacy Mode''').  
The '''GRUB''' is used to manage and boot up linux operating systems on computers that use the BIOS system. These are typically older computers or those that did not come with Windows 8 pre-installed. It is worthwhile noting that the UEFI can be disabled on many systems to run using the BIOS instead; this is known as running in '''Legacy Mode'''.  


Computers sold prior to the release and pre-installation of Windows 8 - which introduced UEFI - will therefore use the GRUB.
