This is how my GRUB menu entry looks like

How I can get rid of these unwanted GRUB menu entries. My Ubuntu and Windows is getting loaded properly but these unnecessary entries I don't need it. Thanks in advance. This is how the grub.cfg(/boot/grub/grub.cfg) looks like in my case:

finally i am able to resolve this issue...went thru each and every file under /etc/grub.d/ directory and got rid of the entries not needed and then ran 'sudo update-grub'. I went into 25_custom and wiped all the entries into which were not needed(to boot into at the time of startup - like all the unnecessary EFI entries).

sudo gedit  /etc/grub.d/25_custom
sudo update-grub

Please make sure to make a backup of the files you are editing. Make sure that you are not storing any of the backup files starting with 25_custom...if you store it with 25_custom_today'sdate etc....EFI boot loader will still read the entries from that....For folks who have HP Laptop - this will definitely work for you.Thanks for all your help.

To clean your Grub entry you have to decide which menuentry to remove, First let's edit the custom file script in the /etc/grub.d dir contain same content of your grub.cfg.

gedit /boot/grub/grub.cfg

Copy all contents and go to the file /etc/grub.d/40_custom

sudo gedit  /etc/grub.d/40_custom

Append the copied content to the lines founded in the 40_custom.

Now In this custom file just remove all menuentries that you don't want to appear in your Grub menu. Take sure to remove the node of the menuentry which is enclosed by { }

Now when you finish Save the 40_custom file and exit from gedit

Then run the command:

sudo update-grub

This command will create a new boot menu in the file /boot/grub/grub.cfg that contains the custom menu items that we have specified.

You can check, ahead of rebooting, just to be sure, by using the command: gedit /boot/grub/grub.cfg. This will open the file in read-only mode.

If the file is as you expect then go ahead and reboot else check where you have an error.

  • This is a wrong way for UEFI. – Pilot6 Jul 3 '15 at 17:42

    It looks like grub menu, not UEFI. And did you run Boot-Repair? Boot-Repair adds all the efi files it finds into 25_custom. So you can backup 25_custom and edit at will. Then run the sudo update-grub – oldfred Jul 3 '15 at 18:30
  • Thanks oldfred I will try that...please specify the steps in more details. – Ashu Jul 4 '15 at 6:53
  • @Maythux No that doesn't work...it will in fact make the situation even worse. – Ashu Jul 4 '15 at 6:54

To remove EFI entries from UEFI efibootmgr is used.

You can list entries by
