Boot-Repair
an ultimate solution for frequent boot problems

Boot-Repair is a simple graphical 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.

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.

Getting Boot-Repair

1st option : get a disk including Boot-Repair

The easiest way to use Boot-Repair is to create a disk containing the tool (eg Boot-Repair-Disk, a disk starting Boot-Repair automatically), and boot on it. Remark : it is recommended to install the ISO on a live-USB (eg via UnetBootin or LiliUSB or Universal USB Installer). Do not burn it on a DVD if your computer has Windows8 pre-installed, or if your boot is in EFI mode.

sudo add-apt-repository ppa:yannubuntu/boot-repair

Using Boot-Repair:

Recommended repair:

1. launch Boot-Repair from either :
   • the Dash (the Ubuntu logo at the top-left of the screen)
   • or by typing 'boot-repair' in a terminal
2. 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.
3. If the repair did not succeed, indicate the URL to people who help you by email or forum.

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.
