I just set up bootcamp on my iMac and windows is working great. The only problem is I cannot get back into OSX. I left my apple keyboard at home, and am now using a wireless logitech keyboard and mouse. When I boot up my computer, I hold down the windows key 'option' when the grey screen comes up, but the options of what to boot never comes up. What am I doing wrong? And if its because I need the apple keyboard, is there any workaround? I'll be stick in windows for weeks if thats the issue.
