Welcome to the new Linux Foundation Forum!

i am trying to learn how computer flows thru hdd from bios to finally os partition.

i am confused with how a hdd of linux computer functions.

bios will read the first sector of hdd (sda), from there it obtain info on where are the boot loaders, and from individual boot loader it knows where are the partition and os folder to execute.

can someone who really clear about this make a diagram or flow chart of how the actual fact the computer works on a hdd ?

thx
andrew
