How do I Uninstall windows 7 from a hard drive?

It won't let me delete all the folders from the drive an idk why

You have to take out the HDD, inset it into another computer, and format the drive. I had to the do the same thing once because Lenovo DRM was in it. Afterwards you can do what you wish the newly formatted HDD.


Boot to a USB with FreeDOS and command line format the drive.

If you were intending on just removing Windows and keeping everything else, either connect it to another machine or boot a live o/s from a USB

Otherwise just format the whole drive

You could use on a usb to reformat the partition, or on a CD if you still use those.
