Hi all,

I am trying to install Windows 8 Release Preview. It reboots, saying "Preparing devices for use..." . The screen says "Preparing..." and counts up to 90%, when the screen goes blank, then the Windows 8 logo pops up, then the message "This installation was not successful..."

Do you have any fix? Thanks.

Did you download the ISO file from an approved site? Did you burn the ISO file to a DVD using a slow burn (4X max burn)? Did you boot to the DVD and choose Custom (Clean) install to attempt your installation? These are the approved methods to install Win 8.

Did you check the Win 8 RP Compatibility Center prior to attempting your installation.

You may have a corrupt download of the Windows 8 Release Preview and if so you may be missing some files. Re-download the file and re-burn to DVD to install.
