I used to have Windows 8.1 - Linux Mint dual boot. I succesfully removed Windows from the system but Grub still shows Windows in boot options:

grub menu

I would like to configure the system the way, that on start up I directly load into Linux Mint without seeing Grub screen options at all.

What I tried so far:

  1. sudo update-grub

  2. sudo sed -i 's/GRUB_TIMEOUT=10/GRUB_TIMEOUT=0/' /etc/default/grub

    sudo update-grub

  3. Deleted Windows entry using efibootmgr; it was entry Boot0003, it is no more there:

    BootCurrent: 0002  
    Timeout: 0 seconds  
    BootOrder: 0002,0004,2003,2001,2002  
    Boot0000* EFI Network 0 for IPv6 (70-54-D2-8C-E9-B5)   
    Boot0001* EFI Network 0 for IPv4 (70-54-D2-8C-E9-B5)   
    Boot0002* ubuntu  
    Boot0004* Ubuntu  
    Boot2001* EFI USB Device  
    Boot2002* EFI DVD/CDROM  
    Boot2003* EFI Network  
  4. 3 followed by deleting directory Microsoft from /boot/efi/EFI.
    Currently /boot/efi/EFI has three dirs left: Boot toshiba ubuntu

Is there anything else I could do?


Open terminal (Alt+Ctrl+T) and follow the below procedure :

  • Paste the following command in terminal sudo gedit /etc/default/grub. It will open a file named /boot/grub/grub.cfg file.

  • Add GRUB_DISABLE_OS_PROBER=true at the bottom of this file.

    It will prevent Windows being added to your grub menu.

  • Now to write the change, run sudo update-grub

  • You can then run cat /boot/grub/grub.cfg to check that your Windows entry has disappeared.

  • Restart your device to check the same.

Note : If above one doesn't go well you can also visit the link Removing Windows entry from grub.

Happy Ubuntu :)
