Cannot launch grub-customizer

Asked by HabsFanInOz on 2013-05-26

I recently upgraded to Ubuntu 12.04 from 10.04 using the upgrade functionality in update-manager. I have a dual boot set-up with Windows XP on /dev/sda and Ubuntu on /dev/sdb. After the upgrade, grub wouldn't work (it went straight to the grub rescue prompt), but I solved that by going to the BIOS boot menu and booting Ubuntu from there. I then installed grub-customizer and used it to install grub to the MBR, and everything worked fine when I rebooted - I got a splash screen with menu entries for both OSes.

However, now when I try to launch grub-customizer (using sudo grub-customizer), I get the following error message popping up in a box:

>please Inform the author about this problem. The following information could be helpful:
>exception '15AssertException'
> with message 'found unexpected file on path: /etc/grub.d/20_memtest86+'
> in /build/buildd/grub-customizer-3.0.4/src/Model/ListCfg.cpp:952

Also, the output at the terminal is as follows:
Ubuntu1:~> sudo grub-customizer
 *** initializing (w/o specified bootloader type)…
   * reading partition info…
   * Loading Framebuffer resolutions (background process)
   * Finding out if this is a live CD

   * re-activating 10_linux
   * re-activating 20_memtest86+
   * re-activating 30_uefi-firmware
   * renaming PS_memtest86+

Any suggestions?

The update added some duplicates which caused problems (however the fallback behaviour of grub customizer fails here… that's odd. 'll fix it in future releases.).

Please remove these files:

Then you should be able to run grub customizer successfully.

Thanks a lot - after removing those files, grub-customizer launches successfully.

I had a simmilar problem, I think it was:

I am not sure about the version any more but it was this file.
I renamed it into 10_linux_dead and GRUB-Customizer startet, it took a long time to load but it worked.

This is what I made my GRUB look like:
(It's not possible to screenshot the GRUB :p so it's 2 pictures.),Ds69ORy#0,Ds69ORy#1

Thank you Daniel Richter for that great tool :-)
