Microsoft released the Windows 8 developer preview a few weeks ago, during its famous BUILD 2011 conference. Since then, we've shown you what this OS has to offer, how to upgrade from a Windows 7 terminal and even dual-booting for those who cannot part with their favourite Windows 7. The last part could have been done by splitting the existing partition or by creating a VHD. Although this trip has shown you how Microsoft is going to rethink the portable world, this pre-beta version has its limitations. Today, we are going to show you how to uninstall Windows 8 from a dual-boot configuration.
This guide starts by presuming that you followed our steps to get Windows 8 up and running alongside Windows 7 and that no other operating systems are present. We are going to mess with some booting registries so make sure you follow our lead as presented or you may end up with an unbootable PC.
1. While in Windows 7, download EasyBCD and install it using default settings.
2. Launch the application and under the "Edit Boot" menu, delete Windows Developer Preview and then save the configuration.
3. Now select Windows 7 and click the checkbox next to it and make it as the default boot option. After you press on "Save Settings", select the "Skip the boot menu" option and save once again.
To test and see if that was successful, restart the computer and then follow the rest of our guide. As you can see, you may only choose one path, depending on your current configuration. As a warning, everything stored in the Windows 8 drive will be completely lost.
Path 1: For the classic dual-boot
1. Press the Start + R button, to open the Run menu.
2. In the Run window, type "dismgmt.msc" and hit Enter.
3. Right click on the volume that stores Windows 8 at this moment and choose to delete it. When finished, a black headed volume will appear in the middle of the window.
4. Right click on the disk with a BLUE header and choose to extend its volume.
5. Using default settings complete the wizard and the computer will be back to its past state.
You can see that the main drive just got a bit larger, a sign that our modifications were successful.
Path 2: For VHD junkies
1. The first thing to do is delete the VHD drive you previously created, which has a .vhd extension. This file will be found on the root of the C:\ drive or, wherever you've chosen to save it.
As we stated in the title, this is the easiest method to get things back to previous state (i.e. before Windows 8 was installed). If you change your mind, you can always install Windows 8 right-back or wait for a decent beta version.
