Fixed: Thanks Phatt1e!
Okay let's get into the details.
When I turn on my computer all that it shows is a black screen with a blinking white underscore in the upper left. For about half a second it says in the bottom left to press ESC to enter the Startup Menu. Very annoying because I only get half a second to press it.
Os is Win7,
Startup Menu

System Recovery
Goes to a screen that says 'Windows is loading files...' and a load bar.
After that, it does 'Starting Windows' like it normally would if the computer was working.
HP Recovery Manager Screen pops up
HP Recovery Manager:
Microsoft System Restore (Restore didn't work)
System Recovery (Gets to a point where it restarts the computer, returning to black screen blinking underscore)
Minimized Image Recovery (Gets to a point where it restarts the computer, returning to black screen blinking underscore)
Run Computer Checkup (Can open a command prompt window here, if I can do anything with that?)
Show Contact Information (Hp website for customer support)
File Backup (I don't even care about any of the files on my computer right now)
Command Prompt is called
Administrator: X:WINDOWSSystem32cmd.exe
It can't find files like explorer.exe so does that mean I deleted my OS somehow?
Either I get help from you, or I send my computer off for a month to get fixed. Im sad.
