Windows 8 Load Driver During Install Help!

I'm new and need some help haha. I need to reinstall Windows 8 and it tells me that I need to load a driver before the install can begin. I have no idea how to do that or where to find the driver for my computer (HP ENVY m6 1125-dx). I know for a fact that its my hard disk driver... SATA driver? Anyways, thanks for the help in advance!!

"I know for a fact..."

What's the exact error message?


Is it "A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now."


If so, see support.microsoft.com/kb/2755139 :

"A required CD/DVD drive device driver is missing" or "A media driver your computer needs is missing" error message when you try to install Windows by using a Windows installation DVD or ISO file
