- Worked for me, not the way everybody expect but with some patience I think this app can fix many boot issues, I did have issues with boot-repair since the beginning from not detecting BR to 'successfully fixed' (when it wasn't), but after many attempts finally succeed, the problem with BR is this. Almost all the resources in the software are dedicated to fix Ubuntu and little resources for Windows, you have to change some things manually in advanced settings to tell BR where you want the MBR to be installed/fixed, in my case I wanted primarily fix the NTFS partition. I just make my account to write this review to show my gratitude to the developers, THANKS!!
- Worked fine
- No source code published, no way to generate your own image. For all I know this steals all your passwords and sends them to the author, installs hidden bitcoin miners or trojans, etc. Hasee drivers free download. Stay away from projects that don't publish their source code.
- Used tuxboot to create bootable boot-repair usb. Then rebooted with that usb stuck in a usb port. After a GRUB2 screen and several minutes, got nice gui with boot-repair screen saying Scanning systems (mount) This may require several minutes.. followed by progress bar, but that progress bar seemed frozen at about 40%. After what seemed like 20minutes and no change in progress bar, I finally stopped it and logged out.
This tutorial will guide you on how to rescue, repair or reinstall a damaged Ubuntu machine which cannot be booted due to the fact that the Grub2 boot loader has been compromised and cannot load the boot loader which transfers the control further to the Linux kernel. In all modern Linux operating systems GRUB is the default boot loader.
This procedure has been successfully tested on an Ubuntu 16.04 server edition with the Grub boot loader damaged. However, this tutorial will only cover Ubuntu server GRUB rescue procedure, although the same procedure can be successfully applied on any Ubuntu system or on the majority of Debian-based distributions.
Here's a couple of example Grub2 entries. Chainloader doesn't work to boot an ISO at present, so these entries must (1) use loopback to 'mount' the ISO, and (2) add something like iso-scan or findiso to the linux line that specifies the ISO file. Unfortunately, there's no generic way to do this. Each different boot entry must be customized to the target ISO's contents. Copy ISO files. Now copy the ISO files of various distributions like Ubuntu, Debian, Linux Mint etc. To the /multiboot/isoboot folder. Use a file manager like Nautilus, Dolphin, etc. Or do it with the cp command. Ubuntu ISOs are designed to allow booting directly from the hard drive using GRUB 2 and eliminates the need for burning a CD/DVD. This feature permits the user to boot and use the 'Try Ubuntu' feature of the Ubuntu installation CD as well as to install Ubuntu directly from an ISO on the hard drive.
Requirements
You try to boot your Ubuntu server machine and you see that the operating systems no longer starts-up and you discover that the boot loader program no longer works?

There are a lot of methods in Linux that can be used to re-install a broken grub, some can involve the ability to work and restore the boot loader by using the Linux command line and others are fairly simple and implies booting the hardware with a Linux live CD and using the GUI indications to repair the damaged boot loader.
Among the simplest methods, that can be used in Debian based distributions, especially on Ubuntu systems, is the method presented in this tutorial, which involves only booting the machine into the Ubuntu live DVD ISO image.
The ISO image can be downloaded from the following link: http://releases.ubuntu.com/

However, it’s unimportant if your time zone is not correctly detected, because you are not performing a system installation. Just press
Yes
to continue further.11. On the next screen you’ll be directly transferred into rescue mode. Here, you should choose your machine root file system from the provided list. Michigan driver's license renewal cost. In case your installed system uses a logical volume manager to delimit partitions, it should be easy to detect your root partition from the list by reviewing volume group names as illustrated in the below screenshot.
Otherwise, in case you’re not sure which partition is used for the
/(root)
file system, you should try to probe each partition until you detect the root file system. After selecting the root partition press [Enter] key to continue.Choose Root Partition

14. On the next screen, type your machine disk device where the GRUB will be installed and press [Enter] to continue, as shown in the below image.
Usually, you should install the boot loader on your first machine hard disk MBR, which is /
dev/sda
in most cases. The installation process of GRUB will start as soon as you hit the Enter key.15. After the live system installs the GRUB boot loader you will be directed back to main rescue mode menu. The only thing left now, after you’ve successfully repaired your GRUB, is to reboot the machine as shown in the below images.
Installing Ubuntu Grub Boot Loader

15. On the next screen hit Continue by pressing [enter] key in order to open a shell in your root file system partition.
Open Shell Mode
16. After the shell has been opened in the root file system, execute ls command as presented below in order to identify your machine hard disk devices.
After you’ve identified the correct hard disk device (usually the first disk should be
/dev/sda
), issue the following command to install the GRUB boot loader on the identified hard disk MBR.After GRUB has been successfully installed leave the shell prompt by typing exit.
17. After you’ve exited the shell prompt, you will be returned to main rescue mode menu. Here, choose the option to reboot the system, eject the live bootable ISO image and your installed operating system should be booted without any issue.
