for u r case, MBR will reside in C drive. usually MBR will be stored in first sector of a primary partition. so before formatting primary partitions please be carefull !!.

u can create max 4 primary partitions(default limit).

if u choose to install windows in d drive(logical drive) then also the MBR will be written
in c drive becoz c drive is default primary.

before formatting c drive take the backup of Boot.ini file in cdrive c:\boot.ini (it is a system hidden file) and replace it back after formatting and installing xp in c drive.
