Windows 7 wont boot up, black screen with blinking cursor..

After upgrade on my HP probook, windows7 will not start. All I get is a black screen with a flashing cursor. I do not have the discs for Windows 7 and I have never done a back-up to my computer on discs or other hard drive.

1. This computer was ordered for me by the VA for my schooling.

2. All that is available upon start up is the HP system check and restore to factory settings by pressing the escape key.

3.Norton Anitvirus came with the computer and was installed when I received it.

Please give me some hope, for this computer for all of my school related work is gone.

Why is my screen black when I start Windows 7?

References to Vista also apply to Windows 7.

Saving any needed data and re-installing Windows 7 might be the best option though here are a
few others.

You can save your files by putting the drive in another computer or an external drive case and then
backing them up. Do so using several methods in a redundant manner. Of course a real computer
shop or your System maker can help recover the files.

Or you could use an Ubuntu boot CD to back up the data.

Can you access Safe Mode? Repeatedly tap F8 as you boot? If so you can try Control Panel
- Device Manager - Display Adapter - Double Click on - Driver tab - click UPDATE driver -
then Right Click on Device and UNINSTALL - REBOOT.

A method to try to access the desktop (try in both regular Windows and Safe Mode) is to CTRL +
ALT + DEL - Task Manager and on Process Tab find EXPLORER.exe and END PROCESS on it - then
on Applications Tab - lower right - New Task - type in EXPLORER.exe. Safe Mode is reached by
repeatedly tapping F8 as you boot up. CTRL + SHIFT + ESC also starts Task Manager.

First check this thread in case its a simple one and if not come back to this thread.

Black screen issues are extremely tough to repair and any fix is usually on a hit or miss
basis. That there is no information on a black screen like there is on a blue screen just
adds to the difficulty. Often using a restore point nor startup repair will have any effect.

cover a wide field of efforts.
