I have a computer that i'm wanting to install windows 10 professional on. I have nothing but a keyboard / mouse and the CD drive hooked up to my PC, with the windows 10 pro disk inside. It will ask me to press any key to boot from the CD. Now it goes to the purple screen where it has the windows logo. Takes about 30 seconds and you see the dots that go in a circle. It makes one to two full rotations then pauses, restarts my PC and does this again.
I decided to put the windows 10 installer on a flash drive and try it that way. It does the same exact thing. It will not go farther than the dots in the circle. Just resets my pc every single time with not error messages.
It's a Z77 sabertooth asus mother board. 3770k cpu , 7970 radeon 8 gigs of gskill 1866 mhz ram.
