Disabled AMD display adapter to use onboard graphics and got a black screen

[jwillis]

So I disabled the AMD driver in an attempt to get GTA 5 running on onboard graphics but I got a black screen and now windows boots up but does not show anything on the screen but a frozen boot logo, what I would like to know is keyboard shortcuts to re enable the display adapter in windows 7 home premium sp1.



Edit: I am able to load the bios on my system by mashing f2 but I'm not sure what setting to change, I have a Lenovo y40-70 and I have windows 7 and 8 in dual boot

Are you able to boot into safe mode?

I am not able to boot into safe mode without the screen freezing

Did change the graphics output setting in bios? If not switch it to onboard graphics

And make sure you switch the dvi/vga/hdmi cable to the onboard connector.
