This is indeed interesting. AFAIK your ProBook 640 G1 is not compatible with an M.2 SSD.

Take a look at the following Maintenence & Service guide.

What slot did you put it in? Was it a WWAN slot?

I have not explained well, my pc recognizes the disk m.2, I have 3 operating systems installed on it and they work fine as long as the boot disk is the hdd or a usb. If only the disc m.2 does not start
HP Recommended
Yes on the WWan / m.2 port
HP Recommended
Also in the BIOS itself there is an option to put an SSD disk in port m.2 but not an option to boot from it
HP Recommended

Can you take a digital picture of that and post it here so I can see what you mean?

IMG_20170310_094722_719.jpgHere is the bios option to insert an m.2 ssd

HP Recommended

it should be a way tu manually write a path in bios that boots m.2 like in menu F9

HP Recommended

That would involve hacking the BIOS. 

 

The BIOS websites will be a place to find out how to do that or to have it done.

 

 

There is, of course, a risk involved and it is all yours.
