Do you have a Win7 DVD which came with your Acer, or just Recovery Disks?
Have you tried running the Recovery partition by tapping the keys given on first screen to Run Recovery? YOu can read more about how to run this by looking up your Manual at the Acer Support Downloads webpage for your model.
You should not have to install a SATA driver for Win7 and certainly not for Recovery disks.
