HI!
My HP notebook fails to start windows (black screen).Now i have 2 video cards the (amd 6770m and the intel one),in the past we did manage to fix the problem by formatting and removing the amd card driver.
Now i did format the notebook, but i dont know how to delete/disable the graphic driver card...can you please help me.
Thanks.

PS: I can't access to the desktop,and i can't open safe mode (beacuse i need to complete the installation after the format).

Unsure why that or the dead link in your next post.

As to formatting the laptop, this is done by using the maker's restore media. Installing Windows from scratch would have to have HP reveal all the steps. I have a guide but folk want more. Nod to HP.

Hi!
Is there a way to format without installing the graphic driver?
Or is there a way to remove graphic driver with command prompt or regedit?

The answer to your questions, I'm afraid, is "no" to both.

Why not remove the offending videocard during the install and add it later?

Format is what it is.

Formatting a drive is dead simple. Since no OS is installed, one can format the drive in another PC and now you have a blank formatted drive. Done.

Unsure why that would be of any use to some.

As to the next question, unsupportable. It's so advanced that if you don't have a lot of years on Windows then it's no. Best exit is to use the maker's restore media. Folk can lose months trying to get around this. Why work hard? This could be solved in about a hour if the machine's hardware is good.
