So I just installed the Gnome, I used the Gparted to make the partitions because the basic mode to install side by side with windows was not working. Ok, I made the partitions and installed, no problem. But the dual boot it's not working, runs directly the Windows 7. The bios setup I also can't config the 2nd boot with the Ubuntu partition, only shows the first one and de DVD drive. My motherboard it's a Gigabyte Mini.
I tried to found here someone that had the same problem but no results.
Anyone can help? Thanks!
