Laptop blackscreen after installing SSD

[Amir_52]

My laptop is ASUS ROG GL552VX. I already updated BIOS to the newest version.
So, when I installed Samsung 950 PRO m2 nvme SSD my laptop screen just gone black with only the cursor on loading when I started it. After entering BIOS the SSD is not detected at all.
Not even restarting or startup repair could do anything. Resetting CMOS also do nothing.

If you have cloned your old disk onto new 950, most probably boot information is not correct. Boot with Windows install DVD/USB, and repair boot.

No, I just installed the SSD, didn't even cloned it yet. And the SSD didn't appear in boot order in BIOS
