yesterday I installed ubuntu 14.04 in my windows 8.1(preinstalled) lenovo 14R willing to dual boot it with windows 8.1.I created a different partition and a 2gb partition for swap. Though i did NOT DISABLE FAST BOOT of windows 8. I am a new linux user and I have no idea of fixing it. Now I can only boot Ubuntu and when I choose windows boot manager (instead of ubuntu in the begining) i see this screen:
/EndEntire file path: /ACPI(a0341d0,0)/PCI(0,13)/Sata(0,0,0)/HD(2,1f4800,82000, 03b335deed640d49,2,2)/File(\EFI\Microsoft\Boot)/File(bootmgfw.efi)/EndEntire error: cannot load image Press any key to continue. . .
i followed the instructions of this video. http://www.youtube.com/watch?v=hOz66FC0pWU
The only thing that was different was that at 8:40 there wasn't anything like dev/sda1/windows 8(loader) in the menu that is in the video.
Thank you in advance for your help.
