I have a Toshiba laptop with Windows 7 Ultimate. When I turn on the computer, after a few seconds a black screen appears with blinking cursor. In order to avoid this problem I press Ctrl + Alt + Delete, which restars the computer. I then keep pressing the F8 key which brings up the black screen with options such as "start windows in safe mode", "start windows normally" etc.
Is there any way to make my laptop working normally again?
