These are executable code. 16bytes per partition * 4 = 64bytes + (0xAA55) 2 bytes for MBR Marker = 66bytes 512 - 66 = 446 bytes > When this routine is executed ? Just after POST.

And the all book i had read said the mbr load the loader grub How ? And the grub launch the kernel, ok . How this grub is load ? By which programm ? > So, i would like that someone give me the names of routines, the order of their launching and which load or execute what until the grub exécution ? I would suggest work it floppy on qemu/bochs first to understand then gradually move on to partition tables and boot loaders. Read “Understanding the linux kernel” - System Startup chapter for thorough understanding.
