hi guys, can anybody finally resolve this for me and everybody else who is suffering this problem. trying to install win 8 in bootcamp on my late 2012 iMac 21.5, 2.7GHz i5 8GB ram. done everything, installed all the software, and my purchased legit copy of win 8 using usb 2 flash drive. everything goes perfectly, mouse and keyboard working perfectly right up until the customise screen then NOTHING! no keyboard, no mouse, nothing! i know this has been asked and covered by thousands of folk having the same problem but every solution hasn't worked for me. i have been searching all over the net for weeks now and nothing works. i also know there are some brilliant guys on here who could hopefully help me and others with the same problem. oh, and i was originally using a usb 3 flash, and read that it solves the prob if you use usb 2. it doesn't.
