OMG guys that worked
i just searched on the internet that how to fix bad sectors and found that win7 has builtin option for error checking for hard disk[ as gollum also said] so i just started it it showed me bunch of the errors and also fixed them so after that i tried running winxp setup on that hard disk on which i ran error checking and VOILLA it worked . i love you guys <3 [ m not gay btw] without you guys i would have never know that it was due to bad sectors on my hard disk <3
. and whitestar_999 i was already checking it about a week and the values of yellow attributes is not increasing
i think i just need to start error checking tool on all the partition of my hard disk so it will fix them too
. and thank you whitestar_999 , rijinpk1 and Gollum and also all those who repplied you guys rock. =D <3 and also sorry for my bad english
