(I am not an advanced user)
I used to have a dual boot system - Win7 and Ubuntu 12.04 - Everything was working fine.
My motherboard blew up. I had to replace it, and they installed Win7.
I tried to install Ubuntu 13.04.
The install apparently recognized that my disk had Ubuntu 12.04, because it accepted to UPGRADE to 13.04.
Continued install until the end.
After that, I tried to boot the system, but ONLY Win7 will boot.
I am really stuck now. (Win7 works fine, but I miss Ubuntu)
Should I try to install Ubuntu 1304 from scratch?
Thanks in advance.
