Windows 8 HP Pavilion dv7-4285dx Upgrade results in black screen after intallation finalizes.

Question

I have a 2011 HP Pavilion dv7-4285dx with Windows 7 64 bit Home premium installed.  The notebook/laptop has a AMD Radeon HD 6300M series display adapter with driver version 9.2.2.0 dated 9/27/2012 and an ATI technologies Intel HD Graphics display adapter with driver version 8.7771.1.0.  The notebook/laptop has not had a hardware upgrade and contiains the orignal factory OS. BIOS is current to latest available.
The issue I had while upgrading to Windows 8 is after the install finalizes (settings and preferences are entered) and the system boots to the tiles screen, the display works fine.  Clicking to the desktop works only for a few moments before the screen goes dark. Pressing the power button and/or closing/opening the lid results in at times a black screen (no power to the screen) or black screen (power to the screen) or a black screen where only the mouse pointer is visible and moves around the screen.  Restarting the computer results in a repeat of the issue at times while other times it will boot directly to what appears to be the windows desktop. You can interact with the file folder icon on the task bar as well as internet explorer, and you can get the charms bar and tile screen. Any attempt to open computer management or any control panel or task manager will open the window as an icon on the task bar.  You can mouseover the icon to "preview" a small version of the window but you can not click on it to maximize.
I attempted the following workarounds:
1) Clean install of Windows 8: Installs but fails with same result as above
Refresh PC from windows 8 rescue media: Works slightly longer until AMD driver fails and then reverts to situation above. 
2) Uninstalling all display adapters (via computer management) and then upgrading to Windows 8: Results in microsoft drivers getting installed, works much as refresh above until AMD driver fails and then reverts to above situation.
3) In Scenarios 1 and 2,  I also tried to use windows update within Win8 to update the drivers there are updated MS drivers available ,(dated as late as 10/27/2012) but intalling those drivers also resulted in a failure of the adapter within a short period of time as did NOT updating the drivers.
4) Disabling display adapters and then restarting:  Results in a BSOD (Blue Screen) IRQL_NOT_LESS_OR_EQUAL Stop: 0x0000000A error during boot as the OS runs into trouble with the driver before Windows 7 boots.  This happens if one or both drivers are disabled.
5) Disabling display adapters before in-place upgrade to Windows 8 results in the Windows 8 equivalent of a BSOD and results in the system shutting down and then reverting to Windows 7.
Through research, I determined some ppl had luck connecting another monitor/HD TV through VGA/HDMI and then using the function-screen button to switch, with my system this resulted in the same issue displayed on the TV/Monitor. There are also updates to ATI and Catalyst center available including drivers and installing these do not remedy the issue. Intel was checked and there are no drivers available as HP uses a "custom" driver for intel.  Attempting to install any of these Intel drivers will result in a fail with a compatiblity error.
Windows 8 has no safe mode ability from the windows 8 rescue media disk, you cannot F-8 as you could in the preview. Safe mode must be reached via charms, settings, startup and then selecting safe mode as a boot option, which is not available as the display adapter malfunctions.  In those scenarios where I was able to get a windows desktop to boot up as in the first paragaph I can get to the restart settings via charms, but clicking to bring up the restart menu requires another window to open which is only visible as a "preview" on the windows task bar.
if you are going to attempt to try any of these,
1) Use a third party software to image your pre-win 8 upgrade system that you can boot into from USB or CD;
2) Before starting the process, disable the UAC prompt and remove any passwords from logon, as those things will require you to interact with the OS and you will not be able to do this when the adapters fail.  The screen will shadow out as it usually does but the prompt will not be viewable.
3) Create an ISO image of the Win8 install media and write down the product key. If you are able to get a successful boot, before the drivers fail, create a Windows 8 rescue media disk.
I spoke with HP tech support this morning (10/29/2012) they are aware of the issues and they lie with the display adapters.  They are working toward a solutuion but there are none available at this time and no date when they will be available.  They recommend checking the support website and having the web page autoscan your PC as the drivers will show there when they are posted and they will be installable from Windows 7 so there will be no issue with upgrading to Windows 8.  Bottom line, do not upgrade to Windows 8 at this time.
MS Tech support escalation tier reps also informed me there is no present workaround available.
Hope this helps and saves somebody some time!

 My laptop sat at BestBuy from Friday night until today (10-31-12)! They couldn't figure out how to fix the problem so I finally told them to revert my latop back to Windows 7! I hope HP reads these and will hurry up and make the updates needed so that I can run Windows 8 on my Laptop! I just bought mine in July of last year there is nothing wrong with it and after dropping about $1200.00 for my dv7-4285dx along with the Best Buy Geek Squad package I do not feel like having to drop more money into another laptop!! PLEASE HURRY AND FIX THIS I DIDN"T DROP $69.99 plus tx to not be able to use Windows 8! Even before I did the upgrade I had the GEEk Squad check to make sure I could make the upgrade and was told this laptop well surpasses the required minium to run Windows 8!!!!!!
