I downloaded the Windows 8 Developer Preview from http://msdn.microsoft.com/en-us/windows/home/ and tried to install on Virtual PC, but got the following error.
Your PC ran in to a problem that it couldn’t handle,and now it needs to restart.
You can search for the error online: HAL_INITIALIZATION_FAILED
Try these and you will be up and running Windows 8 Developer Preview :)
