Comment: Probably this is a change in add-apt-repository, but in utopic, every PPA you add it appends the word ubuntu after the first word.

Boot-Repair is a simple tool to repair frequent boot issues you may encounter in Ubuntu like when you can't boot Ubuntu after installing Windows or another Linux distribution, or when you can't boot Windows after installing Ubuntu, or when GRUB is not displayed anymore, some upgrade breaks GRUB, etc.
Do not use it for a system that uses EUFI/SecureBoot! It hasn't been updated to handle that.
Boot-Repair lets you fix these issues with a simple click, which (generally reinstalls GRUB and) restores access to the operating systems you had installed before the issue.
Boot-Repair also has advanced options to back up table partitions, back up bootsectors, create a Boot-Info (to get help by email or forum), or change the default repair parameters: configure GRUB, add kernel options (acpi=off ...), purge GRUB, change the default OS, restore a Windows-compatible MBR, repair a broken filesystem, specify the disk where GRUB should be installed, etc.
Boot-Repair is a free software, licensed under GNU-GPL.
Getting Boot-Repair
1st option : get a disk including Boot-Repair
The easiest way to use Boot-Repair is to burn one of the following disks and boot on it.
Boot-Repair-Disk is a disk starting Boot-Repair automatically.
Boot-Repair is also included in Linux-Secure-Remix and various other distributions.
Remark : you can also install the ISO on a live-USB (eg via UnetBootin or LiliUSB or Universal USB Installer).
2nd option : install Boot-Repair in Ubuntu
- either from an Ubuntu live-session (boot your computer on a Ubuntu live-CD or live-USB then choose "Try Ubuntu") or from your installed Ubuntu session (if you can access it)
- connect to the Internet
- open a new Terminal, then type the following commands (press Enter after each line):
sudo add-apt-repository ppa:yannubuntu/boot-repair sudo sed 's/trusty/saucy/g' -i /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list sudo apt-get update sudo apt-get install -y boot-repair && (boot-repair &)
Note: if you are running 14.10 (utopic) you have to replace the second command with the following
sudo sed 's/utopic/saucy/g' -i /etc/apt/sources.list.d/yannubuntu-ubuntu-boot-repair-utopic.list
Using Boot-Repair
Recommended repair
- launch Boot-Repair from either :
- the Dash (the Ubuntu logo at the top-left of the screen)
or System->Administration->Boot-Repair menu (Ubuntu 10.04 only)
- or by typing 'boot-repair' in a terminal
Then click the "Recommended repair" button. When repair is finished, note the URL (paste.ubuntu.com/XXXXX) that appeared on a paper, then reboot and check if you recovered access to your OSs.
- If the repair did not succeed, indicate the URL to people who help you by email or forum.
Advanced options
Warning: the default settings are the ones used by the "Recommended Repair". Changing them may worsen your problem. Don't modify them before creating a BootInfo URL, and asking for advice on Ubuntu Forums Absolute Beginners Section or in Installation and Upgrades.
