I have backed up this OS using Easeus Todo Backup and Macrium Reflect.
What I want to do now is as following.
The original 500GB drive has about 400GB free. I want to create new partition on that drive and use my backup software to restore my Windows 7 Pro image to that partition.
Then use this software
to alter the boot loader configuration so that when the PC boots up, the use is offered the choice of the original Windows OS or the new one.
Is this possible? If not then I guess I am going to have to partition the 500GB drive and do a new Windows installation on the new partition which will be a pain and let Windows create the boat loader configuration.
