Before you open this error report below notice what is underlined in the error report, that is a concern for me and I am clueless about it. I have just updated my computer to windows 8 pro, after this transition over I had to update my drivers from preventing minecraft from giving me a similar "...because it failed to find an accelerated OpenGL mode" error. So I updated all the drivers and this error message still appears. This one odd "Windows NT" thing is my suspected problem, but again I have no clue nor am I an expert. I call for help! I keep trying to update these drivers yet no noticeable outcomes. I have a ATI Radeon HD 4200 (Microsoft Corporation - WDDM v1.1)
Bad video card drivers!
-----------------------
Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

Windows 8 updated to WDDM 1.2, which breaks OpenGL functionality on older graphics cards. The built-in WDDM 1.1. graphics drivers will not allow for GPU acceleration in Photoshop, for instance. In my case it’s a Radeon HD 3650 Mobility, which is no longer supported in the official Windows 8 drivers from AMD. So, if you own one of these cards in your computer (desktop or laptop), the following instructions will, I hope, be a remedy.
AMD Radeon HD 4000 Series (x64 | x86)
AMD Radeon HD 3000 Series
AMD Radeon HD 2000 Series
AMD Radeon HD Series AGP
ATI Radeon 9500 Series (x64 | x86)
ATI Radeon 9550 Series
ATI Radeon 9600 Series
ATI Radeon 9700 Series
ATI Radeon 9800 Series
ATI Radeon X300 Series
ATI Radeon X550 Series
ATI Radeon X600 Series
ATI Radeon X700 Series
ATI Radeon X800 Series
ATI Radeon X850 Series
ATI Radeon X1050 Series
ATI Radeon X1300 Series
ATI Radeon X1900 Series
ATI Radeon X1950 Series
ATI Radeon Xpress Series
ATI Radeon X1200 Series
ATI Radeon X1250 Series
ATI Radeon X2100 Series
Although it has only been tested with Windows 8 x64, it should work the same for x86.
Find your graphics card in the list above, and download the corresponding driver. Run the installation until the very end; ignore any error messages.
[Anyone with the Radeon HD series, please jump ahead to section (A), further down]
Download the ATI MobilityModder and install it. In both cases, create a new folder on C:\ (ATI or AMD). When it is finished, copy this patch to C:\Program Files (x86)\MobilityDotNET, and replace the present EXE file.
Run the ATI MobilityModder from the Start Screen, and then select C:\ATI\Support\10-02_legacy_vista32-64_dd_ccc as your location, and let the program do its thing.
Right-click in the bottom left corner of your primary screen (Windows + X), to open an elevated Command prompt, and type the following commands:
bcdedit /set {current} testsigning on
bcdedit /set {current} nointegritychecks true
Close the elevated prompt.
Return to the Start Screen, start typing gpedit.msc and hit Enter.
Navigate to User Configuration (2nd node) | Administrative Templates | System | Driver Installation | Code signing for device drivers
Double-click the policy and set it to Disabled.
Restart your computer.
(A) For AMD Radeon HD:
After Windows is fully booted, navigate to C:\AMD\Support\12-6-legacy_vista_win7_64_dd_ccc_whql\Packages\Drivers\Display\LH6A_INF\CH_95951.inf and right-click it, then select Install.
Just wait a few seconds, and your screen should start flickering. After a while, a small dialog will appear, saying The operation completed successfully.
After that, you double-check the driver in the Device Manager. It should have the driver date: 2012-07-03.
You’re done. Maybe do a quick restart.
( For ATI Radeon:
After Windows is fully booted, navigate to C:\ATI\Support\10-02_legacy_vista32-64_dd_ccc\Packages\Drivers\Display\W76A_INF\C7145534.inf and right-click it, then select Install. You will get the familiar red dialog warning you about installing unsigned drivers. Throw caution to the wind and continue.
Right-click in the bottom left corner of your primary screen (Windows + X), to select Device Manager.
Expand the Display adapters section. You should see Windows Basic Display Adapter. Right-click it and select Update driver software.
Click Browse my computer for driver software and then Let me pick from a list…
Your new driver should already be there, along with the already present Basic Display Adapter and WDDM 1.1 driver options. Select the one with your graphics card’s name, and no additions in parentheses. It will say that it’s not digitally signed. Simply ignore this, and click Next to install it.
Right-click in the bottom left corner of your primary screen (Windows + X) to open an elevated Command Prompt, and type the following commands:
bcdedit /set {current} testsigning off
bcdedit /set {current} nointegritychecks false
Last, restart your computer one final time, and everything should work fine. There might be a few graphical errors in the “Metro” part of Windows 8. Adobe GPU acceleration and OpenGL games work great, though.
tbh i don't think it matters what card you have, doing the whole thing of making sure ythe AMD drivers are set as default would prob help for anyone
