I have a PC with Windows 7 on one disk.
First, I use WUBI to install Ubuntu, but I can not see the ubuntu logo. Then, I try to install 11.10 on the disk, but I get the same result. And then I try to install 12.04 with USB, but I get the same result again.
When I restart the computer and choose to boot from USB, I can see a screen with a gray menu containing some options such as run Ubuntu on the USB, install Ubuntu on disk, and others.
When I choose "install Ubuntu on disk", the computer outputs some lines of text, and the screen becomes a mess. After a little while, the screen's power light goes dark.
