i cant describe inside activities of this methord.it also not in magazine.
i dont know about boot secter well.if you can,describe me.i think boot sector has data and instruction for give to BIOS program.
some time,at formating automatically creat it as Sandun saied.
The boot sector uses the BIOS calls to read disks and do other I/O. It's nothing more than a very low level
API. It's not protected mode it's real mode. There is a extension for this called EFI, Extensible firmware Interface,
which replaces the BIOS calls and it let you to run in protected mode. EFI is used in newer systems.


Formatting does place those 17 sectors , but what does those 17 sectors do is locate the NTLDR in the
root file system and load it. Nothing more than that. So if NTLDR doesn't found, it will report a error message
"NTLDR not found" and reboot the computer.

It's not magical thing, you can dissemble and see what's on your boot sector.

disassemble the code and read the code , have the fun ;)

Old days [windows 95 days, my golden days in computing] we did it using the command 'sys C:\' now just formatting
will do the job.

please note that those 17 sectors is just for locating the NTLDR and load it to the memory and jump to it.
It's won't function as a bootmanager. I don't think somebody can write a complete boot manager inside
17 sectors of code+data space.
