A year ago I bought a new SSD to add to my old laptop (Toshiba Satellite L650D) and it worked very fast until the GPU died. I had to buy a new laptop (Acer F5-573G). On the old drive I had Windows 7 and Ubuntu 14.04.05. On the other computer I connected the SSD to the motherboard and systems start like from my laptop so I thought I'd put this into my new laptop.
And there is a problem: I cannot select system and laptop display that there is no device to boot from there.
How can I get both systems to be be visible without installing everything from the beginning?
