bootsect.exe
============
	Legacy tool for XP. 
	
	Also used to make USB bootable.
	
	Bootsect.exe updates the master boot code for hard disk partitions to switch between /nt60 {BOOTMGR (Vista)} and /nt52 {NTLDR (XP)}. You can use this tool to restore the boot sector on your computer. This tool replaces FixFAT and FixNTFS.
	Bootsect Command-Line Options

	Bootsect uses the following conventions:

	bootsect.exe {/help | /nt52 | /nt60} {SYS | ALL | DriveLetter:} [/force] /mbr

	e.g., to make a bootable USB drive for Windows installations ...

	pushd "s:\boot"
	bootsect.exe /nt60 d: 
	popd

		Where 's:' is source [mounted Windows install ISO] and 'd:' is the target USB drive.
		Then extract/clone the Windows Installation ISO to the target USB drive.
