Could you please tell me how I can deal with that issue ? I would just like to retrieve my Windows 10 OS and if possible remove the GNU GRUB terminal so that I get an automated boot like previously.Thank you very much for your help.
To remove grub and boot directly into Windows, re-install the Windows boot manger.
