Problems while installing Ubuntu 12.04 64 & 32 bits from LiveCd

Solution 1:

The problem is occurring at the graphical window where you are asked if you want to Try Ubuntu or Install Ubuntu. Assuming you've made sure the installation media is good, the next thing you might want to try doing is just skipping that window altogether.

If you hold down the Shift key when you see the keyboard and person icons at the bottom of the purple boot screen, you'll get a menu. (This is the same menu where you may have selected "Check disc for defects.")

Select Try Ubuntu without installing from that menu. This should give you a desktop, without ever giving you the ubiquity-dm window where you are asked graphically to choose.

• There are two ways to choose between Try Ubuntu and Install Ubuntu. One is graphically--the GUI loads, and gives you the choice in a window. That functionality is provided by a program called ubiquity-dm. It looks like the problem might be with that. The other way is to prevent ubiquity-dm from ever showing that window, by choosing which you want before the GUI loads. That's what you're doing when you press Shift and select Try Ubuntu without installing (or Install Ubuntu) from the non-graphical boot menu.

If that works, you can use Ubuntu from the live CD, and you can install it by double-clicking on the Install Ubuntu icon on the desktop or in the Unity launcher (the vertical bar on the left side of the screen).
