Cant finish windows' 7 installation because video card is dead

[JRuivo]

Hey guys, I have a HP G62 laptop, and the main graphic card died a month ago, so to make it work all I did was deactivate the main graphic card, in safe mode , so I could use the board card or whatever. Anyway, I was just doing a factory reset on my laptop and everything was going well til the moment the laptop restarts, and it just goes into some blackscreen forever. I guess it's trying to use the main video card, but it's dead.
I tried to load the computer in safe mode to finish the installation, but it just says "installation cannot be completed in safe mode", so it restarts and tries to go back into normal mode again.
What can I do to deactivate the main graphic card, or to finish installing windows?
I seem to have access to cmd.exe through recovery mode, that's about it.

What were the symptoms when the main card died, and how did you then deactivate it? I'm not quite following what happened and is happening here.

When the card died, the windows wouldnt load, it would just stay frozen at some black screen.
I got into safe mode and deactivated the video card, that way I could log into normal mode using VGA.

After I formatted the laptop I can no longer do the same process because it wont let me go into safe-mode, so Im just stuck with the black screen again before loading windows welcome screen.

I see. The thing to do is to physically pull the video card. The new install doesn't know you don't want to use it. You may have to start the installation over.

The bad video is the onboard chip, right?

Boot to BIOS Setup and see if you can disable the onboard video and make the add-on video the default.
