Hello, I am quite new to building a pc but have put one together and brought legit windows 8.1, when installed to ssd using disc the first time it starts up fine and gets me to the he screen where I can update use apps everything with the disc in, when I remove disc and turn off computer it starts up and first windows sign comes up and then crashes with the background colour the same as my home screen colour! It then does nothing. I thought might be ssd so installed it to my 1 tb hhd and it's the same. I've changed all boot options and removing hhd while using ssd, anyone any ideas ??? I'm all out
