So i just built my new pc, i7 4790k, R9 390, MSI Z97 Gaming Mobo, Kingston V3000 120gb SSD, and WD 1 tb HDD. I was installing windows 7 and then when it finished, it rebooted my computer, ever since i have been stuck on "Starting Windows" every single time I retart my pc. Plus everytime I try to go to safe mode, it doesn't even boot! It stops a checking file disk.sys and does not boot. I'm helpless.. please help. I've tried every windows option.
