You seem to indicate that you've set your BIOS so that the Crucial SSD will be first in boot priority order before you have even begun the disk-cloning operation. Your description of how you approached the disk-cloning operation is somewhat confusing to say the least. I have spend almost 12 hour already to find a solution without much progression. If someone could help mee with this one I would greatly apreciate it. I did the cloning proces all over again once in case something could have gone wrong I have already tried to remove the old Hard drive and boot up with only the SSD conected. I have searched trough a ton of forums for this kind of problem but can not seem to find this one in particular. I have booted up windows with the old hard drive to check if the cloningproces was completed and everything looked fine to mee. At this point it just keeps giving mee the black screen with the weird flickering louding cursor. So I turn of my PC and tried booting it again but this time I don't even get the option to insert my password. When I move my mouse the screen lights up and I can see the cursor with a flickering loading sign. When I started it up the first time it gave me the option to put in my password and log in on my windows account. I used the Bios to make my SSD boot first. I used the Acronis cloning software to put my 460 GB from my old hard drive onto my SSD. I tried to install my new crucial mx300 525GB SSD today, But it seems I can not get into my windows 10 account.
