I had Ubuntu 13.10 installed on my laptop. After I upgraded windows, I tried to get grub back through Boot Repair
via these commands mentioned here:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
But when I run first command I get this error:
Cannot add PPA: 'ppa:yannubuntu/boot-repair'.
Please check that the PPA name or format is correct.
what's the problem?

Simply connect to the internet first and then try to add the ppa again just like before.
I would suggest you to do in terminal:
and then do:
if it doesn't work I would suggest you to add it manually in apt-get
and write this:
deb http://ppa.launchpad.net/yannubuntu/boot-repair/ubuntu saucy main
then save it and update:
