I had ubuntu 14.04.2 LTS installed in dual boot with windows 8 with
grub2 as boot manager. The problem arose when the updated windows 8 for windows 8.1, now
grub is no longer displayed when starting and windows 8.1 is loaded automatically. To be able to access the
grub, it is necessary that when the notebook is booting, press F12 (bios boot options), there is listed, among other things, Windows 8.1 and Ubuntu, only when I select Ubuntu
grub2 screen appears showing the option to select: Windows OS loader, Ubuntu, Ubuntu and advanced options.
So, I wonder what to do to start to load the
grub screen automatically.
Thanks for any help!
