I'm new to Linux, I wanted to install Ubuntu and installed successfully with the Universal USB installer. My notebook has frozen and I was forced to shutdown.
When I started notebook again, it appeared to only boot Ubuntu.
I wanted to have both Windows and Ubuntu and to have possibility to select during the boot.
But unfortunately I can select only Ubuntu.
Now I would like to delete Ubuntu in order to recover all the information that I had on Windows.
I have tried and update-grub, but is not working, I don't have Internet connection.
