I have a HP labtop and my laptop froze all of a sudden so I did a hard restart of the computer. After restarting the computer I am no longer able to boot my computer up, the screen will go black sometimes after the log in screen. But now I do not even get the option to go to the log in screen now it just goes to the startup recovery stage. Everytime I try to fix start up I get startup repair off line following by the details of 0.00000 or something like that. The numbers are all zeros in the details but I tried other options like restoring to a previous point and I keep getting errors. THe computer is about 4 years old also I tried searching online but am having difficulty understanding what is going on.
