Ok, so sorry for the SUPER LATE answer, I was busy this months. I formated my PC and installed Windows 7. The problem keeps happening, so I will pass this topic to Seven Forums...

I ran a surface test on my hard drive, and no errors were found. I couldn't run the test on the "Bad Disk". Actually I can't do anything on it.

If it's not another hard drive or flash drive, what could it be?

It started working know, I don't know why.

I have my HD and the cd used to boot in this screen. Only those. I also have my mouse, keyboard, headset and wi-fi adaptor connected into USB ports.

There are some solutions related to Powershell scripts.
I saw one guy that got the menu fixed, by changing theme to one of the Contrasts Theme, and then reverting it to the original.

What non OS disk? I didn't understand.

essenbe here are the screenshots you asked for:

blueelvis when I try to log in, my computer stays on the windows...

I navigated to Windows folder in cmd and tried to run msconfig. It says that I am not administrator and can't run the program.

"Windows couldn't find 'msconfig'."

Windows isn't loading.

Ok I followed the tutorial, what do I do know?

Oh nevermind, I'm using a pendrive not a cd.

In this tutorial when I type "G:", it says that the device isn't ready.

sfc/scannow says that there is another repair pendent. Chkdsk doesn't fins any errors.

When I tried to reset, it said that an error ocurred, but didn't specified. Automatic repair says that it couldn't repair.

I don't have one

I tried resetting my PC, and it gave me an error. Automatic Repair also gives me an error.

Yes, but when I try to go back on the point, it gives me a error: 0x8007051a

When I type that, it says that no settings were changed.

I entered troubleshooting from windows pen drive, what do I do know?

When I enter this link, it downloads the ISO file, not windows media tool. What should I do with the ISO file?

Not working

How do I know what key should I press? F8 and shift + F8 doesn't work.

You mean keep pressing f9 until something happens?
