Should a bootable partition start from sector 1 on a hard disk?


Should the first bootable partition start from sector 1 on a hard disk? or Can it be created anywhere on the disk? I am using fdisk to create the bootable partition.

TIA

A normal home computer boots to the first bootable active parititon in the chain. I may be getting ideas confused though. You can't easily change the bios and hardwired nature of a PC.

Now don't get confused as to what grub or other loaders do.

The first sector of a disk is usually where the MBR would reside. Once the system has completed its POST, that's where the BIOS has it look for something to boot from. The MBR then points to the bootable image (or Grub in a multi boot system)
From Wikipedia:
Quote:
A master boot record (MBR), or partition sector, is the 512-byte boot sector that is the first sector ("LBA/absolute sector 0") of a partitioned data storage device such as a hard disk.
Play Bonny!
