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:
“The best quality tea must have creases like the leathern boot of Tartar horsemen, curl like the dewlap of a mighty bullock, unfold like a mist rising out of a ravine, gleam like a lake touched by a zephyr, and be wet and soft like a fine earth newly swept by rain.”
—Lu Yu (d. 804)
“A process in the weather of the world
Turns ghost to ghost; each mothered child
Sits in their double shade.
A process blows the moon into the sun,
Pulls down the shabby curtains of the skin;
And the heart gives up its dead.”
—Dylan Thomas (1914–1953)
