Hello, 

I have a little problem with my G7 7590. Currently I have an m.2 ssd and a 2.5" hdd running in my laptop. The windows is installed and running from the m.2 (checked through cmd and disk part). I want to replace my hdd to an ssd. I already bought a Samsung EVO 870,which should be compatible with the laptop. As soon as I replace the hdd with the new ssd, the windows doesn't load and it says that there is no boot device found. In the bios I can see the new ssd, but not the m.2. As soon as I put back the hdd, everything runs nicely as it did before.

 

Any idea? 

 

Thank you in advance!
