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.

UPDATES:

Machine Information:

  • CPU: AMD Athlon II*3 440

  • VideoCard: ATI Radeon HD 5600/5700

So you're not even able to boot from the LiveCD/USB... Mind posting your computer specifications? It might be a graphics-related or power-related issue. The output of text lines during the boot is normal: can you read any of the last lines? maybe they contain useful information... –  Mr. Pixel Apr 6 '12 at 13:27

I download the desktop-i386.iso. Is this wrong?I don't if I should download the amd64.iso. –  zxhfirefox Apr 6 '12 at 13:35
    
Yes, the lines may disappear very quickly indeed. Now since it seems to be a graphics-related issue, have you seen any specific options in the boot menu (the one that shows "Run ubuntu", etc.) related to alternative graphical modes? I don't remember how it's called, but I think the boot menu has an option to let you boot in a lower resolution or in plain VGA... Also, when you say Radeon HD 5600/5700, is that one single card, or do you have two/more cards? If you have multiple cards/adapters, you might want to try to plug your monitor into another VGA/DVI plug (resp. the blue and white ports). –  Mr. Pixel Apr 6 '12 at 13:40
    
Your CPU looks relatively recent, and should therefore support the 64-bit OS. This means that you can install the 64-bit version, BUT you can also install the 32-bit version. You should be fine with the version you downloaded (looking at the filename, it seems like that's the 32-bit version). –  Mr. Pixel Apr 6 '12 at 13:42

What, specifically, are the results? I usually burn the disc image to a CD and then boot from said CD, do any necessary partitioning, and then complete the installation. I've never had good luck with the USB method.

I personally never had any trouble installing from a freshly-created USB disk, following the instructions on the ubuntu Download page (where it lets you choose "I will be installing from a USB disk" or "I will be..."). But I'm insisting, it's better to use a freshly-created USB, and not one that has been created a month ago and on which other files have been added. –  Mr. Pixel Apr 6 '12 at 13:33

@Mr.Pixel What do you mean freshly-created USB? –  zxhfirefox Apr 6 '12 at 13:34

@Mr.Pixel I format my usb disk and use universal-usb-installer –  zxhfirefox Apr 6 '12 at 13:37
    
Yes, freshly created USB means you just used universal-usb-installer. Now I just think of a little detail: while you created your USB, did you select the correct Ubuntu version in the universal-usb-installer? It's stated as "Step 1: Select a linux distribution from ...". If you downloaded the default Ubuntu 11.10 image, you must have selected Ubuntu 11.10 desktop. If you're not sure, feel free to recreate your USB. I know it may sound like a stupid suggestion, but who never made a stupid mistake? :-) –  Mr. Pixel Apr 6 '12 at 13:49
