See this ubuntu appears in BIOS menu (UEFI)

I have this on my Lenovo s205 too.

Is there some way to remove "ubuntu" from the menu? I don't even have it installed anymore.

  • you can try easyBCD app for windows.

    @RonnieDroid EasyBCD is a tool for modifying the boot configuration data in Windows (aka, the Windows bootloader). BCD and UEFI are separate because BCD relies on Windows, while UEFI is OS-independent (still present without an OS installed). Modifying the BCD would be useless because, by default, the only option would be Windows, even if another OS is installed. Commented Aug 22, 2015 at 1:55

You should be able to do this via a Live Ubuntu CD.

Install efibootmgr:

sudo apt-get install efibootmgr

Then add to the kernel EFI support

sudo modprobe efivars

Then run sudo efibootmgr to check your boot entries. It will return something like this:

BootCurrent: 0004
Timeout: 2 seconds
BootOrder: 2001,0003,0005,0006,0000
Boot0000* Lenovo Recovery System
Boot0001* EFI Network 0 for IPv6 (B8-88-E3-84-F3-EF)
Boot0002* EFI Network 0 for IPv4 (B8-88-E3-84-F3-EF)
Boot0003* Windows Boot Manager
Boot0004* EFI USB Device (SanDisk)
Boot0005* ubuntu
Boot2001* EFI USB Device

Then delete the option you don't want. In this example, Ubuntu is entry 5. the following could be called to delete entry 5 and remove it from the BootOrder.

(CAUTION: Before executing the following command make sure you enter the correct Boot entry number)

sudo efibootmgr -b 5 -B 

Further details described here: http://linux.die.net/man/8/efibootmgr

Note: as for anything that changes your bootloader, please ensure you have a good disk image that you can boot with.

Now you should also delete the ubuntu subdirectory in the EFI partition to prevent the UEFI firmware from restoring the entry into the BootOrder.

To do that, first find your EFI partition. Run sudo fdisk -l to see the partitions on all attached drives. The EFI partition has EFI Partition under the Type column.

Suppose your EFI partition was /dev/sda2, then mount it on an empty folder anywhere.

sudo mkdir /mnt/efipart
sudo mount /dev/sda2 /mnt/efipart

Now we have to find the directory Ubuntu or any other distro's name in this partition. It is mostly under EFI/distro_name.

Remove that directory and its contents by (PLEASE MAKE SURE YOU ARE DELETING THE CORRECT DIRECTORY) sudo rm -r ubuntu.

    UEFI may reinstall entry if /EFI/ubuntu folder not deleted from the efi(ESP) partition on drive. Always best to fully backup efi partition before deleting any files or folders.

  • In 16.04 I get a 'permission denied' message when trying to access my mounted efi partition, even with sudo. Any suggestions? Commented Feb 17, 2017 at 20:28

    Using Rufus on Windows 10 I just prepared a USB stick with Ubuntu 18.04 Desktop on it and followed your instructions. It worked like a charm. Commented Jun 29, 2018 at 15:01

    Using sudo rm -r ubuntu will only work if you cd to the correct directory first. Better to use absolute path in the command: sudo rm -r /mnt/efipart/EFI/ubuntu

This answer borrowed verbatim from here)

  1. Run a cmd.exe procescs with administrator privileges
  2. Run diskpart
  3. Type: list disk then sel disk X where X is the drive your boot files reside on
  4. Type list vol to see all partitions (volumes) on the disk (the EFI volume will be formatted in FAT, others will be NTFS)
  5. Select the EFI volume by typing: sel vol Y where Y is the SYSTEM volume (this is almost always the EFI partition)
  6. For convenience, assign a drive letter by typing: assign letter=Z: where Z is a free (unused) drive letter
  7. Type exit to leave disk part
  8. While still in the cmd prompt, type: Z: and hit enter, where Z was the drive letter you just created.
  9. Type dir to list directories on this mounted EFI partition
  10. If you are in the right place, you should see a directory called EFI
  11. Type cd EFI and then dir to list the child directories inside EFI
  12. Type rmdir /S ubuntu to delete the ubuntu boot directory


Run live Ubuntu and type:

sudo apt-get install lilo
sudo lilo -M /dev/sda mbr


In my case, I was stuck on grub rescue. I was trying to fix a friend's laptop where he has deleted all Ubuntu partitions from the dual boot option thinking that's the standard way to wipe Ubuntu. Normally the answer mentioned by @kamal works as mentioned above. But in my case, this time it was a bit different/weird.

There was no Ubuntu directory inside the folder named EFI. I saw four EFI files inside the EFI folder. All of them were representing CPU architecture, and all looked like Windows EFI files. I didn't want to risk and delete the wrong EFI file.

Usually, the Ubuntu EFI file looks like this: elilo.efi. But there was no such EFI file in my case nor the directory with a name of a particular distribution.

I wish I knew this command before, it would have a huge amount of time. It's not usually mentioned in any blog. Good luck.
