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 a priori method is distinguished for its comfortable conclusions. It is the nature of the process to adopt whatever belief we are inclined to, and there are certain flatteries to the vanity of man which we all believe by nature, until we are awakened from our pleasing dream by rough facts.
    Charles Sanders Peirce (1839–1914)
