Hi All,
I was trying to understand the booting steps,
BIOS loads the first sector (MBR) of a bootable device(considering disk
only) in RAM (0000:7c00)and then jumps to that addr to execute the primary
boot loader which in turn loads the secondary boot loader(grub) pointed to
by an active partition in the partition table.
If i m wrong above,please correct me.
Now my doubt is that-
If the partition table has multiple active partitions(in case of multiple
OS) , in that case, are those other partitions are read by the primary boot
loader ,if yes then when??
how does the secondary boot loader(grub) come to know about the various
active partitions in the disk (since it does not read the partition table in
MBR)??
thanks
Raja
