GNU GRUB - Boot Process

Boot Process

When a computer is turned on, the computer's BIOS finds the primary bootable device (usually the computer's hard disk) and loads the initial bootstrap program from the master boot record (MBR), the first 512 bytes of the hard disk, then transfers control to the bootstrap code.

There are two versions of Grub in common use. Grub version 2 is now used by most distro's. Grub version 1 is now seldom seen. This is not to be confused with Stage 1 and 2. Stage 1 is an executable program that loads stage 2, a larger executable program. There can be an intermediate Stage 1.5.

Famous quotes containing the words boot and/or process:

    ... until the shopkeeper plants his boot in our eyes,
    and unties our bone and is finished with the case,
    and turns to the next customer, forgetting our face
    or how we knelt at the yellow bulb with sighs
    like moth wings for a short while in a small place.
    Anne Sexton (1928–1974)

    The toddler’s wish to please ... is a powerful aid in helping the child to develop a social awareness and, eventually, a moral conscience. The child’s love for the parent is so strong that it causes him to change his behavior: to refrain from hitting and biting, to share toys with a peer, to become toilet trained. This wish for approval is the parent’s most reliable ally in the process of socializing the child.
    Alicia F. Lieberman (20th century)
