So I installed windows 10 on my PC yesterday, I used to have windows 7. Today I turned on my PC and it says that I can choose to open my PC in windows 7 but not windows 10. So I thought OK I'll just try that, Then it said an error 0xc0000428 and it won't let me turn my PC on, I press enter and it enters the same loop of saying the error and selecting what version of windows I want to open. Please help quick
