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
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.
