OS bootstraping process

I try to understand os bootstraping process. Some questions are not clear to me. One of them is : How does bootstrap code in Volume boot record know about absolute LBA address of 0 sector of patition where Volume boot record resides?

From stackoverflow
  • The bootstrap code in the volume boot record ("MBR" - master boot record - in DOS/Windows speak) needs to parse the partition table(s) to find out where the partitions start, which is where the partition boot records are located.
