Yesterday I mistakenly made a factory backup on my external hard drive from my Lenovo ThinkPad T-420. It wasted my whole empty space on that hard drive.
Now I want to make another Lenovo factory backup on a 16 GB USB drive or a DVD, but it never allows me to create a backup. When I click on the Lenovo recovery drive, it gives me the following message every time:
You can have only one copy of the Microsoft Window Operating system. The Product Recovery Media Creator will exit now.
