Boot-Repair

http://sourceforge.net/p/boot-repair/home/Home/
simple tool to recover access to your Operating Systems.

• Easy-to-use (repair in 1 click ! )
• Free (GPL open-source license)
• Helpful (Boot-Info summary to get help by email or on your favorite forum)
• Safe (automatic backups)
• Can recover access to Windows (XP, Vista, Windows7, Windows8).
• Can recover access to Debian, Ubuntu, Mint, Fedora, OpenSuse, ArchLinux...
• Can recover access to any OS (Windows, MacOS, Linux..) if your PC contains Debian, Ubuntu, Mint, Fedora, OpenSuse, ArchLinux, or derivative.
• Can repair MBR-locked OEM computer boot if the original bootsector has been saved by Clean-Ubiquity
  Automatic backup of MBRs and partition tables during Ubuntu installation. Makes the Ubuntu installer safer.

  Clean-Ubiquity is a small (<100ko addon="" for="" installer="" p="" the="" ubiquity="" ubuntu=""> It automatically performs a backup of the MBR of:
  1) the partition tables of all disks
  2) the MBRs of all disks
  before Ubuntu's installation. No visible change for the user.
  If one MBR is altered by Ubiquity, Clean-Ubiquity links its backup with the UUID of the new OS.
  This special backup can be automatically restored via OS-Uninstaller and Boot-Repair (see https://launchpad.net/os-uninstaller and https://launchpad.net/boot-repair ).
  This can be extremely useful if the computer is MBR-locked. MBR-lock is a system that can be found on some OEM computers with pre-installed Windows. It is (was?) put in place by some manufacturers in order to fight against Windows piracy, by preventing or making difficult the use of a Windows with a different version from the one that was originally on the computer. MBR-lock is now forbidden in some countries (e.g. France), so it should not be on recent computers. Basically, this system uses data written on the motherboard and/or the MBR. If the MBR has been altered (e.g. by GRUB), this system will detect it and prevent Windows (or the entire computer) to boot.
  Clean-Ubiquity needs 2 preseeds integrated during the ISO building.

  • External downloads
• Can repair the boot when you have the "GRUB Recovery" error message

• and much more ! (UEFI, SecureBoot, RAID, LVM, Wubi, filesystem repair...)

GET BOOT-REPAIR: whatever the systems installed on your disk, choose one of the 3 methods below:

• RECOMMENDED: boot on a Ubuntu-Secure disk, choose "Try Ubuntu", and run Boot-Repair via the shortcut at the left of the desktop. Advantages: multi-languages, ok for Wifi, RAID and LVM, 32 or 64bits, based on recent Ubuntu, the 64bits version is UEFI-compatible.
• OR boot on a Boot-Repair-Disk, choose 32 or 64 bit, Boot-Repair will be launched automatically. Advantages: smaller (~400MB) ISO, 32 AND 64bits compatible. Drawbacks: English only, based on Debian-live so Wifi, LVM and RAID drivers are old.
• OR boot on a Debian (or derivatives: Ubuntu, Linux Mint...) disk, either normal session, or live-CD, or live-USB. Then install Boot-Repair in it, either via PPA for Ubuntu/Mint, or DEBs for Debian.

USE BOOT-REPAIR:
Launch Boot-Repair, 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.
Warning: the default settings of the Advanced Options are the ones used by the "Recommended Repair". Changing them may worsen your problem. Don't modify them before asking advice.
