Can someone familiar with installing this assist me. I have a Sony laptop, had windows 8.1 Pro on it..the installation went just fine, did the upgrade..the last thing that it did that took forever was when it was installing all the settings, etc..and it said "This is taking longer than usual" that finished..it said LETS START..and that was it..now I see this little spinny icon thing that I can move around and the background is like a blue screen nothing is there but I can see the hard drive is working from time to time I just have no idea what its doing is this normal..I dont have SSD so a 5400rpm hard drive I can understand might take some time especially a laptop but this is ridiculous
