How to Uninstall or Detach Windows 8 From Dual Boot Setup

It was a couple weeks ago that I published an article about how to dual boot Windows 8 and Windows 7 using VHD. At that time I showed you how doing this by using the Windows 8 evaluation for developers. As you know this free version of Windows 8 only works for 90 days and after that you have to install a fresh version of Windows 8 again. Today I decided to uninstall Windows 8 developer from my system and install a new licensed version. But to do this I need to remove the old version and its Virtual Hard Drive safely without losing any data from my current Windows 7. The first and most important step is to create a backup from your data in Windows 7 so in case of any problem, you don't lose your current system files, data and information. Follow these steps:

How to Set up Back Up in Windows 7
Step 1

Go to the Windows Control Panel>Backup and Restore>Set up backup

Step 2

In the next window, select where you want to save your backup. It’s better to save your backup on an external hard disk or DVD, otherwise choose any drive that you want to store your data.

Step 3

The rest of process is straightforward and easy, just follow the Windows instructions.

How to create a system image

In the same window that you made a backup of your data, click on the "Create a system image" link and in the next window; select the location that you want to store your data. Again I recommended using an external hard drive or DVD for your backup. But you also have the option to use the same hard disk. By having a backup of your system files and data, now we are ready to start with removing the Windows 8 from our dual boot setup.

How to Uninstall the Windows 8 from dual boot configuration
Step 1

To remove the Windows 8.vhd, first of all you need to open msconfig or the System Configuration tool. To open System Configuration, type "msconfig" in the Windows’ Run or in the Start’s search box and hit the Enter key.

Step 2

In the System Configuration window, navigate to the Boot tab. If the Windows 7 is not your system default operating system, then make it your default OS.

Step 3

Select the Windows 8 and then the Delete button to delete the Windows 8 boot entry. After that OK the window and restart your system.

Step 4

Now let’s remove our VHD (virtual hard drive) partition. Open the Windows Disk Management by writing "disk management" in the Start’s search box or type "diskmgmt.msc" in the Windows’ Run box.

Step 5

In the Disk Management window, right-click on the Win 8 VHD partition and from the menu, select "Delete Volume".

Step 6

Click the "Yes" button in the next window to delete the Win 8 volume. The volume will be deleted and an unallocated free space will remain.

Step 7

Again right-click on this disk from the left panel window and from the drop-down menu, choose "Detach VHD". In the next window, tick the option "Delete the virtual hard disk file after removing the disk" and hit the OK button. That’s it, you all done.
