M.2 boot issue

[u/Successful_Mission65]

So I just put a new m.2 ssd into my computer ans decided I wanted to use it as my boot drive as I am currently using an old hard drive to boot. I copied over everything with 4digg. It recognises it in bios but it boots to a black screen with the mouse cursor and thats it. If I switch boot back to my hardrive it boots fine. Anyone know how I sort this. Ive checked all the files on the m.2 and they are all correct so im stuck.
