Hi i have a dual boot between windows and ubuntu 14.04. After updating my windows i realized my grub was lost and windows would directly boot. Something that i am familiar with and know. So i then downloaded the 14.04 iso. Then created a boot able pendrive and ran the live version.
These are the instructions I followedgrub-mkconfig -o boot/grub/grub.cfg grub-mkstandalone -o boot.efi -d usr/lib/grub/x86_64-efi -O x86_64-efi -C xz boot/grub/grub.cfgThen in osx:sudo bless --device /dev/disk0s4 --setBootI think that on initial installation I ran the command above as one and then last night ran it as two.
