SSD Plus not visible on HP 655 laptop

It’s plugged into the internal SATA 3 on the HP655 laptop and it is nowhere to be seen on the bios screens.  When you try to boot up the the screen just says “no bootable device found”.  If I put the same SSD into a Packard Bell laptop it loads up with Win 10 no problem in a few seconds.

I have tried disabling secure boot, legacy mode etc and makes no difference.  I was wondering if the bios is misinterpreting the fast response of the SSD as some sort of error, if I put a SATA 3 HDD (from which I had cloned the system onto the SSD) in the same slot it works fine.

HP have made useful suggestions liek “have you plugged it in properly!!”

Any suggestions welcome.

ps the SSD has the latest firmware according to Dashboard.
