I'm trying to make a dual boot with Windows/Ubuntu, but after I installed Ubuntu I can't boot from USB anymore!
I'm trying to use Boot-Repair, but the problem is it asks me to run a command that refers to a package with no installation candidate!
Here is the command with the error:
sudo apt-get install -y --force-yes grub-pc linux-generic
Package 'grub-pc' has no installation candidate
Problem solved!
Only closed and opened again the boot-repair, choose different repair options on advanced, followed the steps and Vualá!
Done. Now i can dual boot.
Thanks for the reply!
