Okay guys, I'm really stuck. My desktop PSU went bad probably about a year ago, (I thought the computer was completely fried) so I took out the HDD and began using it as an external hard drive. I formatted it, and used it however I needed it. I finally got around to repairing my desktop, and it now works. So I formatted the HDD again, and put it back into the desktop. When I attempt to install Windows 7 via a disk, however, I get this error: "No drives were found. Click Load Driver to provide a mass storage driver for installation." I attempted to find drivers and install them onto a USB to allow me to use the HDD, unfortunately none of them worked though. I have absolutely no idea what to do now. Any help would be appreciated! Here are some specs: HP Pavilion a824n PTGD1-LA motherboard Western Digital WD Caviar SE WD2000 One final note: When I click "Load Driver" then click "Browse" it detects the HDD, so I don't believe the HDD is faulty. Thanks again!
