Boot Camp: Stuck on lock screen
Hey, so I've recently wanted to make a partition and install windows 8 in my iMac, so I got an ISO image from here: http://windows-8.soft32.com/free-download/.64-bit edition. After some time, I managed to get windows running, but I noticed that there wasn't a Boot Camp setup file in the USB that I used to install the Boot Camp files (Before I installed Windows, I had the files on my USB, after installing it, there weren't the Boot camp files anymore). So, I decided to install the Boot Camp files from the apple website on another computer, moved them to the USB, and inserted the USB into the IMac with windows, and ran the Boot Camp setup file. Then, it asked me to restart (like I had seen in tutorials) so I restarted my computer, but when it started again, I got to the windows 8 lock screen and got stuck there, neither my mouse nor my keyboard work so I can't do anything, literally it's just that screen and nothing else. Does someone know what can I do? I'm really nervous and stressed because it's the only desktop computer I have and I really like it. It doesn't matter if I can't get Boot Camp working, I just want my computer to be usable.
Also, sorry if my english is bad, english is not my native language.
Please help!
iMac, OS X Yosemite (10.10)
