I'm trying to install Xubuntu on a computer with windows7. I downloaded Xubuntu and made a bootable USB key with success. During installation process I got a message like this and then it stopped

The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the install system will not boot.

What am I supposed to do here?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • You said installation was successful, then said it was running...! please be clear. Were you trying to install it on USB? – Anwar Sep 3 '16 at 10:06

    Actually I used the wrong words. I could download xubuntu on a USB key, with success. Then I tries to install it on my computer wich has windows seven, and this message about the grub appeared – Sanama Sep 3 '16 at 10:57

Did you try following this guide UEFI? It really helped me out. Seems to me that you need to go into Boot Menu in you BIOS and select the UEFI: USB Hard Drive.
