I installed a Samsung ssd 850 evo on my 3 month old dell 8.1, it ran extremely fast , no issues at all. I was so satisfied until the operating system crashed. I tried to reinstall the hhd and I get this error 0xc0000225, computer needs to be repaired. Computer will not let me do anything. I did put the original hhd back in and it seems to run ok. As before I cannot put the hhd in.
