well yes, but what does it repair? Grub2, Grub legacy, mbr made by windows or some UEFI things or what is it for exactly?

[YannBuntu]

it can do all you said, and more

- reinstall and update GRUB (1 and 2)
- purge GRUB
- choice to place GRUB in MBR or partition
- restore generic Windows (XP, Vista, Seven) MBR (other tools I know don't work with Vista/Seven)
- restore original MBR (required when computer has MBR-tatoo)
- auto detect separate /boot
- detect RAID, GPT EFI
- compatible Debian, Ubuntu and derivatives
- can be used in live-CD, live-USB and installed session (see https://help.ubuntu.com/community/Boot-Repair )
- compatible whatever the architectures (32/64bits) of OS detected on the pc
- automatically solve several GRUB/Wubi bugs
- generate BootInfoScript report (automatically uses the very last script) in 1 clic
- repair filesystems (linux AND windows)
- a nice and intuitive GUI
- ...
- most important of all : automatic selection of best choices to repair the boot in 1 click !

Boot-Repair is free (GNU-GPL), and will soon be included in Debian repositories.

What exactly is the expected result? I was having boot issues and was stuck at the grub promt and after running this disk I just get a black screen after reboot saying:

No System Disk or
Disk I/O error
Press a key to restart

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key

I almost had the issue resolved after a day of working on it and now I'm afraid things are worse.

Hi SES1,
first check the md5sum of the ISO you downloaded, you can find the md5 by clicking on the (i) icon of this page: https://sourceforge.net/projects/boot-repair-cd/files/, and the tool to check the md5 here.
If it is correct, please burn the CD with a slow speed.
Then boot on the CD, you should see this screen appear:


Then choose 32 or 64bits, according to your PC architecture. This will run Boot-repair automatically. No change will be made on your PC boot until you click the "Apply" button.
Then select the "First repair", or go to "Advanced options" for customized repair. If any doubt, select the "Create BootInfo" and indicate us the URL so that we can advise you.

Thanks for your response. I ran the boot info script and this results are posted in this other thread: http://ubuntuforums.org/showthread.php?t=1832261. From what I can tell now, it is a software issue not seeing the partitions on my disk rather than strictly a grub issue as I thought before. Beyond that, I don't really know what's going on.

I am trying to install Ubuntu 11.04 on my laptop. I've actually removed Win7, and reformatted the Hard Drive. I have one large partition on the drive. I've installed Ubuntu from Ubuntu live on my flash drive. When I attempt to boot the computer from the hard drive, I get the "error: no such device:" message.

I downloaded the Boot-Repair tool and installed it on another flash drive with unetbootin. When I start the computer from Boot-repair, I get to the start menu, but no matter which boot option I choose, I get Boot Failed! Unknown file system type on /dev/loop0.

Hello gizmojo, and welcome among us !

Please follow the ISO md5 check steps I described in my previous message.
You can also install Boot-Repair on your flashdrive's Ubuntu, as described in the Documentation: https://help.ubuntu.com/community/Boot-Repair

I used unetbootin to put it on a USB and checked the md5 but I keep ending up on a "initramfs" prompt

[YannBuntu]

hello princetrey, I just checked with Unetbootin and I don't have this error. As an alternative, you can try Ubuntu Secured (it's an Ubuntu ISO containing Boot-Repair) via LiliUSB creator or via USB-Creator (the tool included by default in Ubuntu).
