I download ubuntu-13.04-desktop-amd64.iso and write on a DVD then check it with a MD5 checker and it's OK. I decide to Install Ubuntu on my PC that have Windows 7 sp1 64-bit simultaneously. I follow this manual from Ubuntu website.
In step 4 when I choose "Install Ubuntu alongside Windows 7" and click continue my screen turn black and DVD would be ejected and When I press Enter the system would be restarted.
Also in windows I can't use wubi, When I Run wubi with administrator permission it show nothing, I try wubi.exe --force-wubi and did nothing.
I have this problem with Ubuntu 12.04.2.
