INACCESSIBLE_BOOT_DEVICE After installing new SSD

[eecano]

Hey guys I recently purchased an SSD and installed it on my computer it is a Samsung 850 Pro. I used the Data Migration tool to clone my OS and then shutdown. I switched my current drive with it and turned the pc back on and got the INACCESSIBLE_BOOT_DEVICE error. Any help would be great!

You shouldn't have to clone your OS, do you still have the original windows disk or key usb? If so install it using that method.

Well I got it to work now but it is still very slow to load up!
