Restore Windows 8 from a .wim file

1) Download the WAIK (W7 version is fine) 2) copy file IMAGEX.EXE from the WAIK to a directory -- use the correct IMAGEX file for the Windows you want to restore -- it sits in the TOOLS directory of the WAIK. (AMD64 for Windows 8 x-64, or the version in x-86 for 32 bit version. Don't use the one in the IA directory). 3) then simply run the command : imagex.exe /apply install.wim 1 d:\ (d is the assumed drive you are using for your target system and the .WIM is the name of your .WIM file --I've just taken as an example the standard "INSTALL.WIM' file that exists on the install media for Windows 8 Consumer Preview). Note this must be a device (can be a USB etc) which already has an ACTIVE partition on it. You'll also need to create the Boot image after the WIM has restored run bcdboot.exe d:\windows /s d: /f ALL (assumed d is the device where you have restored the WIM image via imagex). You will actually need a Windows 8 system to create the boot record --the W7 version of this program has slightly different parameters So the easiest way if you don't have a Windows 8 system is just quickly install a "Mickey Mouse" one -- takes about 10 mins - 15 mins -- doon't bother with finding drivers etc -- all you want it for is to run the bcdboot command and then you can get rid of it. You could even use a VM.

Unexplained black screen using Windows 8

This may be why. Okay I just came across some new information that I think explains the random black screens I get sometimes in Windows 8. I've seen it trying to start Flight Simulator X for example. Makes sense since in Windows 7 starting FSX you always get message that aero has been temporarily disabled but not in Win8 because it's not possible to turn it off Application fails due to graphics and display issues Since Desktop Window Manager (DWM) is always on in Windows 8, some older Windows XP era apps can fail if the app uses mixed mode graphics APIs, as in using both GDI and DirectX APIs to draw to the screen (mostly older games), and tries to use full screen mode: DWM will prevent painting directly to the desktop and the game or app will either fail, or draw a black screen on to the desktop and none of the graphics will be visible In such cases, when the app quits, Windows detects that the app or game has a problem with full screen mode, and applies the DXMAXIMIZEDWINDOWEDMODE compatibility mode that allows the app or game to run in a maximized windowed mode instead of a full screen mode.
