I select "Install Ubuntu" and nothing happens. Every time it seems like it's working, then the screen just goes blank with a little line symbol blinking in the upper left corner of the screen.
When you say you select "Install Ubuntu", is this the same button that you can select after the loading screen?.
If so, I would suggest re-downloading and re-burning the CD/DVD as there can be errors in the process of downloading.
You can check if the download completed successfully, this page should help:
Otherwise, if you pressed a button on boot screen where there are 2 icons and have been given a menu of choices, I would then press F6 and go through each option on the list it gives you. Try to boot through any combination of those options.
You may have gotten a similar situation I had with an old desktop where I had to enable the noapic mode for it to boot and load the kernel.
After install, if you have a dual boot of windows and ubuntu, then you need to edit the commands before booting by pressing c at Grub menu and add the option you had to use for install for it to boot. (Image Below)
