It seems your keyboard is working since the pic you sent last night showed 'prepare to enter setup'. How long did you let it try to enter the setup?

It could be a good idea to disconnect any external devices that you do not have to have.

This problem should not be related to any software you installed yesterday since you are not getting to Windows yet. But, the fact that you connected a new drive yesterday does seem to be part of the problem. Did you reboot at all after installing the new drive? I think somehow the boot order might have gotten altered when you connected the drive.
