I have seen a couple guides that spoke about uninstalling ubuntu and have tried following the guides provided in AskUbuntu.
I have installed Ubuntu 14.04.1 LTS from an usb drive and have chosen to install it on same drive/partition.
I then have tried to remove ubuntu first under the windows uninstall programs screen. The ubuntu logo was on there, however when I clicked on it to install it errored out and states that this program is not available. After that the icon disappeared.
After that I did a search on the C drive for ubuntu items and folders and saw the wubi uninstalled. I ran that program, and if finished successfully. However, when I restarted my laptop the ubuntu start-up menu still appeared and asked if I wanted to run either ubuntu or windows partition like earlier.
Is it possible to completely remove Ubuntu from Windows 7 using an ubuntu usb stick (same process that I used to install Ubuntu side by side with Windows 7) and if I can would that affect windows 7.
Also I have seen OS-Uninstaller mentioned in some of the other guides. Would that be risky if you are trying to remove Ubuntu OS while also logged into Ubuntu OS?
Thank you for your help.
