What you can try is do an upgrade installation.For this you need to insert the Windows 7 DVD in your CD/DVD drive and then run the installation from your windows Vista desktop.

You need to go to Start-> Computer -> Right click on your CD/DVD drive -> Left click on Autorun -> Select Upgrade.

If there is no Autorun then you need to go to your CD/DVD drive and double click on setup.exe.Did you see the message like Hit any key to boot from DVD drive?
