Alienware M17x R4 Windows 8 INACCESSIBLE_BOOT_DEVICE after windows update

Hi There,

I sincerely hope you can help. I've rebuilt this bugger a number of times and I still get the same issue.

I've just recently purchased an Alienware M17X R4 and LOVE IT. However I can't seem to upgrade the thing to Windows 8 pro.

I've done a clean install of Win 8 pro using various guides on the dell community & support site using the recommended drivers.

Now here's the funny thing..

When I do a clean install with the recommended drivers it works all the time. The OSD works with all the buttons etc. No issues..

Note that I'm not using the standard Alienware AMD drivers for my GPU as I just go direct to catalyst 13.6 beta but I'm not sure if that effects it.

No issues until I run windows update to bring it up to speed with all the latest fixes.

After the reboot for the update, it BSODs and gives me an INACCESSIBLE_BOOT_DEVICE.

I've done with with both dual boot (with windows 7) and single boot (W8 only) and I get the same problem.

Always after the update.

Now when it BSODS, I can get into the recovery console (after Shift-F8) a number of times and I can run Windows 7 and see the W8 partition no problems.

So the machine itself and it's hardware is FINE as I'm running it now in W7 Mode.

Has anyone encountered this problem? I've made backups so I can go back to pre-updated windows 8 and try solutions.

Hope you can help.

Thanks
