Windows 7: Disabling a Radeon Video driver in Win7 will not boot to the OS

Disabling a Radeon Video driver in Win7 will not boot to the OS

Elsewhere I had a question about installing a PCIe video card to a failing
motherboard with onboard video.

Before shutting down, I disabled the installed driver at the Radeon entry.
Previous expectation was that the HD would boot to 640 base video until
a new driver could be installed.

What went wrong?

Is it possible to recover from this error from a CD or will I have to lose
the data?

Repair install stopped at the same place probably looking for video. I've tried everything I can think of including loading the HD on another machine, asking for Safe Mode and then would turn the driver back on. No good doing that either.

When it ran in trace mode loading Safe Mode options I did not save the
line at which it stopped.

This is in Win 7. Would a driver reinstall from the factory CD salvage my disk?

What would anyone else do if the "Disable" option were engaged?

How do you know that your onboard video not working.
Have to test with another computer, for your monitor.
Or have you get another monitor to check if your computer working or not.

Also you did not indicate is monitor or TV you are connected to.
Some monitor do fail at times, &or monitor setting is wrongly set.
Also if the cable pin is out &or broken, bent, it may affect the video.

For the PCIe video card it will have a copy of CD with drivers included for various OS.

It is not right to delete the driver, as normal it would not affect if you install another driver.
Additional drivers may not affect the system, it indicate as not connected only.

After trying everything to get the HD back from that wiped driver I may have to wipe it.

Before that is there any bootable cd ISO that can load and drop the driver into win7 where it belongs?

Or can the Win7 win32 or whatever folder be copied to the problem HD?

I can't run the checking routine in cmd where it looks up and compares the files (can't think of it)
on the installer disk because the video cannot be found on the HD

This is a distinct problem from the Radeon/Nvidia replacement. I hope I'm not posting in the wrong thread but it's been a while.

In old XP a repair install would fix these things from the XP repair routine.

Please don't point to me to anything similar in Win7. That has failed completely.

Only disable the onboard video from the BIOS and not from the OS. This will force the motherboard to display via a dedicated graphics card (from the PCI-E slot). If you have uninstalled the driver using AMD Catalyst Utility then it should ask you to restart the computer to boot into a 640 base video, at this point you can now go ahead and install the graphics card into the PCI-E slot.
