Bootcamp - Windows failed to start - 0XC0000428 - Windows cannot verify the digital signature for this file \Windows\system32\drivers\AppleSSD.sys

Trying to install Windows 7 into a MAC mini (late 2014). Follows instructions. After Windows is installed into the partition, the error 'Windows failed to start' appears. Error code 0XC0000428 - Windows cannot verify the digital signature for this file. The file is in this path: \Windows\system32\drivers\AppleSSD.sys

The problem is: Every time I boot up Mac mini, the above error appears. I cannot boot OS X anymore. I am struck.

The MAC mini has 2.6 Mhz I5 processor and 256G SSD, 8G memory.
