Like the title says. Bought a new PC and knowing how god-awful Windows 8 is, I intended to install 7 before anything else. I followed the most authoritative instructions I could find to the letter. Modifying the UEFI settings and what not. This laptop (HP ENVY Elite Quad) has not optical drive, though it wouldn't function if it did have one anyway. It installed and loaded Windows 7, but I noticed that Aero wouldn't load, which I naturally assumed was due to the graphics card having an issue, so I checked display settings, and instead of the Radeon HD 8550 it was SUPPOSED to have, it said something like "primary VGA adapter". Having seen that, I opened Device Manager and clicked to expand the section that would have all of the components listed, and my pulse froze when I saw the little yellow exclamation mark of death, indicating "No driver found". So since I am unable to connect anything to the machine to put the drivers ON the machine, I have no clue where to go from here. Is it as simple as replacing the hard drive with a new one? <- Can that be done?
