Hi Tuloon, welcome to NST.
The recovery disk(s) provided on this site contain no Vista installation files. You cannot use them to reinstall Vista.
They allow you to enter the recovery process to fix a broken boot and are provided for those OEM users with a recovery partition, but no portable recovery media.
You must use your own OEM recovery process to reinstall Vista. (the handbook that came with your PC should tell you how to access it - possibly f10 f11 alt/F10 depending on the particular manufacturer.)
