Linux Boot Process
BIOS loads from the MBR or /boot directory
- The boot loader points to the appropriate boot device for loading MBR info, based on the boot image name selection at the boot loader prompt
- Updates the boot sector information, if needed
Once Linux is selected, the kernel image loads
- The kernel image is mostly compressed, but an uncompressed portion of kernel image contains information on how to decompress the rest of the kernel into memory
- The type of boot is dictated by entries in the map installer configuration file
