When installing Ubuntu 12.04 server from a disc, my system freezes up after the installation comes to Installing GRUB boot loader, with a 50% completion bar and the command "Running "grub-install dummy"... below that.
I've tried this installation in both advanced and simple mode and the installation has frozen at this same spot for at least the past 10 attempts.
I'm having a constant issue when trying to install Ubuntu Server 14.04.1. Every time, the installer freezes at "Running 'grub-install' dummy" where the loading bar is at 50%. The MD5 checksum of the ISO is fine, and I used Windows 7 and Rufus to burn the ISO to a 1 GB USB drive.
