I was dual booting winodws 8.1 and ubuntu 13.10. I have updated my windows BIOS. After that i am always getting into windows. GRUB menu is not displayed.
So, Using UBUNTU 12.10 live CD (But i have 13.10 in my lap), i have repaired the boot to fix this issue.
When i clicked Boot repair, it says "UEFI is detected" I have choosen the recommended repair and it ends up with some commands
sudo chroot "/mnt/boot-sav/sda7" dpkg --configure -a sudo chroot "/mnt/boot-sav/sda7" apt-get install -fy sudo chroot "/mnt/boot-sav/sda7" apt-get purge -y --force-yes grub*shim-signed linux-signed*
After that, On clicking forward in the boot repair, got some error message like "GRUB
is still present. Please try again"
PASTEBIN Ref: http://paste.ubuntu.com/7164372/

OS Type: UEFI
Kindly help guys.
