Hi Ganesh, can u see ur HD in BIOS when u boot ur comp? If u can't, then maybe u didn't set the jumper to slave or cable select, or u didn't set ur HD in BIOS, or maybe there is something wrong with ur HD or ur HD cable.
If u can see ur HD in BIOS, then maybe it hasn't been formatted yet, go to control panel -> administrative tools -> computer management -> then in disk management, u should see ur HD, format it in NTFS or FAT32 then ur windows should be able to detect it.
Good luck
