I'm needing to wipe my computer and basically get it ready to sell, and so I've managed to wipe the disc. However I've had to do so with the keyboard as my tap or click won't work (seems to be a common issue in Disk Utility). Now I'm trying to reinstall OS X, and I make it to the window where I chose the disc to install it on and there is the two arrows that turn blue on the bottom, back and install. I cannot for the life of me figure out how to click install! I'm able to highlight the disc I want but I cant figure out what keys will actually get me to the installation as I can't click the install arrow. Help!
