refit not showing up?

I was trying to install Windows 7 from a USB thumb drive, so I followed a tutorial and everything was going fine... until the part where I installed refit. The installation was fine, but I have two problems. First, when I boot my MBP, I hold down the alt/option button, which shows all the bootable drives. Refit should be there, but it isn't!! I've already tried rebooting multiple times. What could be the issue here?? Secondly, when I press down the alt/option key, there is no refit option, so I simply select the Macintosh HD drive to boot from. However, when I boot from here, it always gets stuck at the grey Apple logo with the spinning circle. But when I shut down the laptop and then let it boot without pressing the alt/option key, the laptop boots into OS X fine... I've tried searching the web and the forum as well, but I don't think there were any issues related to mine.. Can anyone please help??

If it helps, my machine is the late 2011 13 inch i7 model running OS X 10.7.3
