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.

I am sorry if this is a duplicate. Several months ago I managed to get Ubuntu 12.04 working on my laptop together with preinstalled Windows 8. It was quite a complicated procedure and this forum helped me a lot.
The case is that I have not used Ubuntu for several months and now I realized that I do not see the grub menu any more after reboot!
I seem to remember that some Live ISOs and USB installs are (or used to be) able to recognize installed operating systems on whatever PC they're used on, giving you the option to boot to the internal HD from GRUB on the Live ISO or USB. I seem to remember there was some small code that worked with GRUB Legacy. Is there a way to do this in GRUB 2?
Whenever I boot on Ubuntu, I see the entire GRUB menu by default. Is there a way I could make it simply auto-boot if uninterrupted within X seconds? I remember that this was the case on previous releases of Ubuntu, it would only show the GRUB menu if you held down a button during the boot.
How can I make GRUB do this by default and just get on with the boot process?
