[Boot-Repair] Graphical tool to repair the PC boot in one click

[YannBuntu]

Today i saw several cases of "127" or "137" error (eg http://ubuntuforums.org/showthread.php?t=2006319 ) when reinstalling GRUB. This may due to a PPA update done yesterday. Working on it.

If you see someone with this error, tell him/her to use Boot-Repair-Disk or Ubuntu-Secure-Remix, WITHOUT UPDATING the software from PPA.

This should be fixed in the PPA now (package boot-sav >= 3.19-0ppa42).

Thanks to Chris and all people who helped.

For information, I updated yesterday the ISOs containing Boot-Repair:
- Boot-Repair-Disk
- and Ubuntu-Secure-Remix.

@all helpers:

I sometimes see people using grub-install twice, for example:

grub-install /dev/sda
grub-install --recheck /dev/sda

- Why not using "grub-install --recheck /dev/sda" only?
- Are there cases where "--recheck" must NOT be used?

Hi
had a failed update of 11.04 to 11.1,
have a win xp primary drive on sda and a separate drive for linux on sbd.

after failure , did load to a grub screen with access to win xp but clicking on linux got the "black screen".

ran boot repair after booting from live cd

then still no ubuntu access, but windows worked.

tried again last night with boot repair with "recommend" options.
(the c drive has wubi on as well)

http://paste.ubuntu.com/1075580/

now lost the ability to boot into windows or linux( except via live cd)

getting into deeper water.

now loads to a grub screen, but has lost

@helpers: None of us know about the --recheck question, so I will ask to GRUB devs. I'll keep you in touch.

@markwestwood: a failed upgrade results in broken/missing system files. This can be difficult/long to repair via command lines (dpkg, distupgrade..), so I would simply burn a 12.04 CD and reset the system files this way. If any problem, please create a new thread here and tell us the link.

I installed wubi on a win7 pc a few days ago and after installing samba it will no longer boot into ubuntu. At first I only got a purple screen with the dots on it. Then I ran chkdsk in windows and now when I try to boot ubuntu I get a grub prompt. Will your CD help me? I want get some files off this install.
Thank you.

[YannBuntu]

In think so: Boot-Repair will try to mount the Wubi filesystem, and open it in a file browser so that you can recover and backup your files

[lukem]

It appeared to do all of that, but it came up blank. In windows it says that rootdisc = 0KB. I'm afraid that means that I've lost it all.
The boot repair disc worked well though.

Any ideas of a program I could run to try to salvage any of the lost files?

Thanks so much for your help.

For standard Ubuntu install (=non-Wubi), I know that TestDisk is good to recover lost files. But for Wubi install I'm not sure if it can help.
