In this article, we will walk you through the process of removing Windows from the UEFI boot menu after installing Ubuntu. This might be necessary if you have decided to completely switch over to Ubuntu and no longer need the Windows boot option.
To remove Windows from the UEFI boot menu after installing Ubuntu, you need to access the terminal, identify the Windows boot entry using the
efibootmgr command, remove the boot entry using the
efibootmgr -b -B command, delete the Windows folder from the EFI partition, and update GRUB to hide the GRUB menu.
Before we start, ensure that you have:
- Administrative access to your Ubuntu system.
- Basic knowledge of terminal commands.
- Made a backup of any important data.
Step 1: Accessing the Terminal
The first step is to access the terminal in Ubuntu. You can do this by pressing
T. This will open a terminal window where you can input commands.
Step 2: Identifying the Windows Boot Entry
To identify the Windows boot entry, we will use the
efibootmgr command. This command allows you to interact with the UEFI firmware of your system. Run the following command:
This command will display a list of boot entries. Each entry will have a unique identifier such as
Boot0001* Windows Boot Manager. The number following
Boot is the boot number, and the text following the asterisk (*) is the description of the boot entry.
Step 3: Removing the Windows Boot Entry
After identifying the boot number of the Windows Boot Manager, you can remove it using the
efibootmgr -b -B command. Here,
-b specifies the boot number and
-B instructs the command to delete the boot entry. Replace
1 with your boot number:
sudo efibootmgr -b 1 -B
Step 4: Deleting the Windows Folder from the EFI Partition
After removing the boot entry, you need to delete the corresponding Windows folder from the EFI partition. First, identify the EFI partition using the
This command will list all partitions along with their filesystem types. The EFI partition is usually formatted as FAT32.
Next, mount the EFI partition. Replace
/dev/sda1 with your partition:
sudo mount /dev/sda1 /boot/efi
Now, list all the folders in the EFI subfolder of the partition:
sudo ls /boot/efi/EFI
Identify the folder corresponding to the Windows entry. This may be named
Microsoft. Delete this folder using the
rm -r command, which removes directories and their contents recursively:
sudo rm -r /boot/efi/EFI/Windows
Step 5: Updating GRUB
The final step is to update GRUB to hide the GRUB menu. First, open the GRUB configuration file with a text editor such as nano:
sudo nano /etc/default/grub
Next, modify the following lines to hide the GRUB menu:
GRUB_TIMEOUT_STYLE=hidden line does not exist, add it. Save and exit the editor by pressing
X, followed by
Finally, update GRUB with the following command:
After completing these steps, the Windows entry should be removed from the UEFI boot menu, and GRUB should directly boot into Ubuntu without showing the menu. If you need to access the GRUB menu in the future, you can press
Esc while the system boots.
Remember, always be cautious when modifying system files and settings. It’s recommended to have a backup of any important data before making such changes. If you encounter any issues, consult the Ubuntu community documentation or seek help from the Ubuntu forums.
No, the steps provided in this article are specifically for removing Windows from the UEFI boot menu after installing Ubuntu.
No, removing Windows from the UEFI boot menu will only remove the boot entry. Your Windows files will not be deleted.
Yes, you can still access Windows by either reinstalling the Windows boot entry or by accessing the UEFI firmware settings and selecting the Windows boot option.
Deleting the wrong boot entry can cause your system to be unable to boot. It’s important to double-check the boot number before running the command. If you accidentally delete the wrong entry, you can try reinstalling it or restoring your system from a backup.
Yes, you can reinstall the Windows boot entry by using the
efibootmgr command to add a new boot entry. Refer to the Ubuntu community documentation or seek help from the Ubuntu forums for detailed instructions.
Updating GRUB will not affect your Ubuntu installation. It only modifies the GRUB configuration to hide the GRUB menu.
