Uninstall Windows 8 from Dual boot With Windows 7

If you have Windows 7 and Windows 8 on your computer with dual boot (dual partitions, each partition for each windows), and now you decide to uninstall/remove Windows 8 and will use only Windows 7 for future, What must you do?
You have to do the simple trick.

First, you need a  boot manager software, I am using tool/software named :  Easy BCD, go to https://neosmart.net/EasyBCD/ to download.
If you already have other boot manager, you can use it.

• Turn on your computer, choose Windows 7 and install the boot manager on it.
• After installed, run the boot manager (the figure uses Easy BCD).
• Click Edit Boot Menu.
• Choose Windows 8.
• Click Delete.
Click Save Setting, to save the configuration.

• Now you can reformat the drive that contain Windows 8 on it, or you can delete  the partition from the Computer Management menu (Right click on Computer --> choose Manage--> Storage-->Disk Management).

• If in the drive have other data , you can copy/backup first before formating or repartition, or you can do to delete only windows 8 folder from the drive, but will take longer time.

Now you have only  Windows 7 on your Computer.
