[Pedro Hyago Gomes de Sousa Duarte]

When I select one of the ubuntus I have installed, it does not load. This happened from nowhere. After I select the ubuntu OS I got a frozen black screen like if it is loading, but I can't do anything in that screen. I have to manually turn off and on the computer in order to select another ubuntu that a have installed previously. I can access the files of the first ubuntu, but I cant not load the OS.
