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.
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 backup table partitions, backup 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. Boot-Repair should be soon included in Ubuntu official repositories, until then use it at your own risks.
1st option : get a CD 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 CD starting Boot-Repair automatically. (English only, 32&64bits compatible, based on Debian-live so Wifi and RAID drivers are old).
Boot-Repair is also included in Ubuntu-Secure-Remix (multi-languages, ok for Wifi and RAID, 32 or 64bits, based on Ubuntu 12.04 LTS, run Boot-Repair from the Dash, the 64bits version is UEFI-compatible)
2nd option : install Boot-Repair in Ubuntu
- boot your computer on a Ubuntu live-CD or live-USB.
- choose "Try Ubuntu"
- connect internet
- open a new Terminal (Ctrl+Alt+T), then type:
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
- Press Enter.
- Then type:
sudo apt-get install -y boot-repair && boot-repair
- Press Enter
- 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.
