i had seen that before
thts too confusing

anyways i have managed to install windows xp

i used a utility called "partition logic"
search for it ( listed among the top 100 tech products by pc world )

i partitioned using this utility ( it actually runs on top of a small os ) , u have to burn its image on a cd
and then tried installing windows , everything went fine ,
windows copied its setup files to pc and when it should have begun actual installation , it just couldnt boot .

solution to this is -:
boot again using partition logic ,
but dont make partition but write mbr
and proceed with installation

so here i m telling solution to my own problem
