After update to 14.04 I can't boot in Windows 8 and in GRUB I have only 3 options instead of 7 I had previously. Also I tried to repair boot but I can't.
Running: sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
returns me:
W: Failed to fetch http://ppa.launchpad.net/yannubuntu/boot-repair/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.
