  1. Thank you for the solution you provided to this problem. Unfortunately, in a Thinkpad Lenovo X1 Carbon 2nd generation, with already Windows 10 Pro installed, I tried to install Ubuntu 18.04.3. The problem is that the Boot Menu does not show the USB tagged with UEFI, only USB and because of that, as you explained, I got the error that you reported. I tried to install an update to the current BIOS (1.35) from the Lenovo support website but that update (1.39) failed. Thus I do not know what else to do.

    • Hey there,
      I understand your concern and I would really like to help you out in this. May I know which USB Burning tool you had used to create the Ubuntu Bootable USB? Rufus Universal USB Installer or some other tools? If you had used Universal USB Installer, then it can make your USB only compatible with BIOS Mode(Legacy).

      Also, I checked up with the Lenovo community and I found a relevant topic. Please check it out. Lenovo Forums
