Do you have an Windows XP or Vista disc?
If so, install it to the point where you can partition the disc.
Partition the disc, then delete it.
Remove the disc, try re-booting from the Windows 7 disc.

Good luck!!

i did that thing buddy.....using xp cd created partitions and booted with win 7 ......

You needed to make your Recovery disks before wiping the Recovery partition. If you failed to do this then you'll need to order Recov Disks if you ever want to return to factory condition, or find a retail Vista installer to reinstall with the Product Key on your COA sticker which you should back up to keep readable.

You have not wiped your HD if you only deleted partitions, repartitioned or formatted. You need to apply all zeroes to the HD using the tutorial linked SSD / HDD : Optimize for Windows Reinstallation

Do you have the latest BIOS update posted on the Support Downloads webpage for your model computer or mobo? If so, reset the CMOS: http://pcsupport.about.com/od/fixthe.../clearcmos.htm

Enter BIOS setup to make sure the SATA controller is set to AHCI mode, then IDE if necessary.

If install fails again, test your RAM with memtest86 CD for 5-6 passes: http://www.memtest86.com/download.html

Then test your HD with maker's diag/repair full CD scan: http://www.carrona.org/hddiag.html

If you have any further questions, ask back. Otherwise confirm you have tried each step as listed, and if install continues to fail post back the exact error message text.
