So I built a PC from scratch and had an amd motherboard and processor. Recently I bought an msi motherboard with an intel chipset and an i5 to go with it. When I turn it on it says preparing auotmatic repair and.sends me to the "endless boot loop" screen. I have a windows 7 disk and try to reinstall it but it freezes when it shows the starting logo when it says"starting windows" underneath. I had windows 10 before I switched out the motherboards and processors. Plz help. I need to get this fixed soon.
