Uninstalling Linux

Has anyone encountered the dreadful LI during installation of Windows(any form),after uninstalling linux 7.1. The computer gets the same point everytime,then,it asks you to reboot to begin the installation,and the computer stops during the recognition of system hardware.It pauses with and LI ?? This machine used to have Linux 7.1,and 7.2 on it(different times)Am I forgetting something?

Thanks
