I received a refurnished model yesterday,for Christmas,with Windows 7 Professional Installed, of the computer described above.
I have a DVD disk copy of the Ubuntu 16.04 64b lts operating system. So,I put it in the disk drive,hit F10 to go into the bios,changed the boot order to recognize the disk,and saved the changed.
When I put the disk in the optical drive,the bottom light flashed green.
But it would not boot from the disk. It sent me to Windows 7 Professional.
Experimenting further,I could not get the operating system(or the computer or both) to recognize when I had put a blank disk in the player and I could not get the media player to play any disk,let alone recognize that it had been inserted.
I went to the support assistant and,did the check,and downloaded everything,but still,even with the bios setting changed,I can't get it to boot from the disk to install the Ubuntu opertating sytsem.
What should I try next? Thank you.
