Just bought a new laptop that came with Windows 8 installed. Installed 7 right away, but still can't get a couple of the drivers working (function keys for volume and bluetooth). HP doesn't provide Windows 7 drivers for my particular model yet, so I had to try drivers meant for similar models. It was hit or miss. Luckily at least got the most important ones working. I still have to buy a new Windows 7 Key for it. Gonna set me back $55 or $60 buying an OEM copy of Win 7 with a serial.
UEFI is cool. Can't wait to get accustomed to using it some day with a better OS.
