If you're using Recovery disks, then try runnning Recovery from its bootable partition on the HD using the hotkey given on first boot screen. If you'd even mentioned the PC brand we could have provideded the steps by now.
If Recovery won't run from partition then wipe the HD first with Diskpart Clean Command
before running the Recovery disks again.
If Recovery fails again try entering Device Manager to disable any erroring devices to see if install will complete: Device Manager - Access During Windows 7 Installation
If these all fail, then get the superior Clean Reinstall - Factory OEM Windows 7
using the installer provided in Step1 for your licensed version.
