Thanks for the thread I have allready read all of that.
Also downloaded the Lenovo bootable diagnostics and run all tests everything passed.
32bit working fine just not 64bit.
I have now managed to install linux mint 19.1 (64bit) as a dual boot on another computer all absolutly fine just a couple of heart stopping moments but working now, just need to find all the dependencies I need for my developing environment.
Using terminal I get this message

I just do not have a clue about all this.
PS if posted in wrong place please change to the right place.
Can anyone make sense of all that?
