I got a Dell latitude D620 for free recently and the person who gave it to me had Ubuntu 12.04 loaded on it. While updating the update software removed "unessential" packages. Now when I try to boot the screen will display the Ubuntu logo and loading sign for a second or 2 and then go black until we pull out the battery.
I gave it 12 hours overnight and about 10 hours during the day. If I use the boot setup software, I will see that there are 3 non recovery mode Ubuntu versions and three recovery versions. One recovery mode version will run command line Linux only.
I am unfamiliar with Linux so I need the graphical user interface.
I have made no mods to the OS or the laptop. I do not think that the guy before me had made any mods either. This computer use to be a windows corporate machine.
