Blue screen and an error message: “0xC000021A”.
I am using a 500GB Western Digital USB 3.0 Hard Drive with Windows 8 installed on it. It is running on several computers and is working perfectly until yesterday. On start up, it shows the Win8 Boot screen but proceeds to show a blue screen and an error message: "0xC000021A".
I attempted to display Win8 Boot loader using the Options menu but get the same error message. This is common for all-in-one computers and have not yet seen it on a laptop. What could be the problem?
