I have a problem with installing Ubuntu on my desktop computer.
I had Ubuntu 16.04 and Windows 10 dual boot. After one update of Windows, the Ubuntu installation disappeared.
I tried to install it again with Ubuntu Live USB but when I clicked on 'Install Ubuntu' or 'Try Ubuntu without installing' I got the following errors:
