So I'm trying to install windows on my WD PC SN520 SSD . However when I try to boot the laptop with the SSD attached , the fans start spinning but it's just a black screen.Not even the bios shows up. Without the SSD the laptop boots to bios and even the windows installation media can be used . Just that it's completely non functional with the SSD attached. I know the SSD is working because it works on my other system . So what could be the issue and how do I get it working.

    It would help if you would give more detailed information. Like, what generation probook 440 and which SSD exactly ?

HP ProBook 440 G4 supports M.2 SATA SSDs only. It isn't compatible with NVMe drives.

According to the HP ProBook 440 G4 specifications it supports:

M.2 (NGFF) 2280 solid state drive

"NGFF", in layperson's terms, is another name for SATA and that means it doesn't support NVMe drives and the symptom you're experiencing is the result of that, as expected. This specifications are also expected considering the hardware's age. Later generations of the same model had NVMe support.

Please note that both types fit the same M.2 slot but unless explicitly mentioned you can't use NVMe drives in any M.2.
