I see that many people have successfully used OS-Uninstaller, but I was not so lucky.
I had installed Ubuntu on a an old refurbished Optiplex 960 SFF that I had upgraded to run Windows 10. The computer uses a bios instead of UEFI, and Grub worked correctly to boot me into either Ubuntu or Windows. I had a mysterious recurrent problem with my computer freezing up when running Ubuntu, but not Windows, so I used OS-installer to uninstall Ubuntu. Unfortunatetly, after doing so I got an error message from Grub and was unable to boot into Windows, which I then reinstalled using the whole disk. Didn't lose much data or figure out what went wrong.
The moral of the story? Any time you install or uninstall an operating system, realize that you might lose everything on the disk and have to start over from bare metal, unless you are prepared for what may be a long and painful journey through disk backups, and the details of Grub and partitions.
