I'm having a huge issue with my father's build where when we installed the Intel 660p 512 gb M.2 into his Maximus IX code it will take about a minute of black screen of the windows logo and then comes the blue Screen saying we couldn't boot up and an error saying CANNOT BOOT UP or something like that. We copied the SSD into the M.2 with Windows 10 Operating System, and other stuff   We went to the BIO's and switched the booting SSD from M.2 to our  original one from the SSD.  We can't figure out why the M.2 with the exact files, and operating system from the SSD. If you have any suggestion on how to make the M.2 work with the operating system and boot up normally tell me. :)
