Re: hp Recovery windows 8

You're very welcome.

Just go to your  dm1-4400sa's support and driver page and get the drivers you need.

But first...Install this driver and reboot.

I see your model has AMD hardware, so you will have to get the chipset and usb 3.0 drivers directly from AMD at the link below.  You want the first file listed.

Let me know if you need any additional assistance.
