Cloned hard drive to SSD but black screen when booted

“Recently, I purchased an SSD and try to replace my old HDD with it. I just cloned my OS drive to the SSD. However, when I tried to boot it from the SSD, all there is a black screen with a cursor that is constantly loading. The most frustrating thing is that I am unable to get into bios or troubleshoot through windows unless I unplug the SSD completely to force it to boot through the old drive, which boots and functions perfectly fine. Any idea on how to get it up and running?”
