The laptop was purchased in February 2015 with Windows 8.1 pre- installed. A couple of months later, I installed Ubuntu 12.04.2 from a usb install stick which I had created, alongside the Windows 8.1 system.
The installation worked fine as a dual boot system even though I had to go to the boot options menu to select Ubuntu until yesterday (14.09.2015) when the option for Ubuntu from the boot options menu was not amongst the boot options available! Therefore, I backed up the files that I required to a usb drive and proceeded to try a fresh re-install of Ubuntu 14.04.2 alongside Windows 8.1. However, this time, the installation was unsuccessful at the point of creating the grub configuration file, the installation process returning a "fatal error" at this stage! I am now going to try several different options in Terminal given in the askubuntu.co forum as follows: Option 1 - sudo grub-install /dev/sda; sudo grub-mkconfig -0 /boot/grub/grub.cfg Option 2 - sudo apt-get install grub-efi Option 3 - Type "grub" in Terminal, hit tab a few times, looking for "grub-efi-install" or "grub2-install" or something ending in "-install" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1495570 Title: Re-installation of Ubuntu 14.04.2 LTS alongside Windows 8.1 failed.
