After a recent update, I get multiple entries for same linux kernel version in the boot menu. I have tried running update-grub2 but it also lists the same linux-image version twice i.e

adnan@adnan-laptop:/boot$ sudo update-grub2
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.32-26-generic
Found initrd image: /boot/initrd.img-2.6.32-26-generic
Found Windows 7 (loader) on /dev/sda1
Found linux image: /boot/vmlinuz-2.6.32-26-generic
Found initrd image: /boot/initrd.img-2.6.32-26-generic
Found memtest86+ image: /boot/memtest86+.bin
done

As you can see vmlinuz and initrd are found multiple times. But there is only one vmlinuz and initrd file in /boot

adnan@adnan-laptop:/boot$ ls -l
total 15120

-rw-r--r-- 1 root root 4050080 2010-11-24 15:58 vmlinuz-2.6.32-26-generic

Can some one tell me why does update-grub2 finds vmlinuz and initrd twice? and how to stop this from happening.

UPDATE: Find grub.cfg here

    The command is update-grub and not update-grub2 i guess.Could you post the contents of grub.cfg ? Also have you created any custom grub files in /etc/grub.d ?

    @karthick87 update-grub2 is just a wrapper for update-grub, so it shouldn't make any difference.

  • binW, I think you have to run: ls -la /etc/grub.d, because you may have there two ##_linux file. These scripts looks for OS-s when you update grub. Update your question with that output!

  • Yes. After posting the grub.cfg file I analysed it my self too and found that there are two *_linux files. So I changed permission for 10_linux to not-executable. After that I ran update-grub and it fixed the problem but I still dont know how I got two ##_linux files there. I didnt have that problem before the update.

Reset to default

How I thought, you had two linux image finder in /etc/grub.d, remove one, the right list is:

00_header 
05_debian_theme 
10_linux 
20_memtest86+ 
30_os-prober 
40_custom

These scripts looks for OS-s when you update the grub.
