How To Fix Dual Boot PC Directly Booting to Ubuntu Instead of Showing GRUB Menu

Ubuntu 11

When you have a dual boot setup of Ubuntu and Windows, you should typically see a GRUB menu each time you boot your PC. This menu allows you to select the operating system you want to use. However, sometimes, you might encounter an issue where your PC boots directly into Ubuntu, bypassing the GRUB menu. This article will guide you through three potential solutions to fix this issue.

Quick Answer

To fix a dual boot PC directly booting to Ubuntu instead of showing the GRUB menu, you can try updating the GRUB configuration in Ubuntu, using EasyBCD on Windows, or using a bootable USB with the boot-repair utility.

Solution 1: Update GRUB Configuration

GRUB, or the Grand Unified Bootloader, is a program that allows your computer to boot into multiple operating systems. If your PC is booting directly into Ubuntu, it might be due to a misconfiguration in the GRUB settings.

Step 1: Open Terminal in Ubuntu

First, you need to open a terminal in Ubuntu. You can do this by pressing Ctrl + Alt + T on your keyboard.

Step 2: Edit GRUB Configuration File

In the terminal, enter the following command:

sudo gedit /etc/default/grub

This command opens the GRUB configuration file in a text editor. sudo is a command that allows you to run programs with the security privileges of the superuser, while gedit is the text editor.

Step 3: Modify GRUB Configuration File

In the configuration file, look for the line GRUB_HIDDEN_TIMEOUT=0. This line is responsible for hiding the GRUB menu. To disable this, insert a # at the start of the line to comment it out. It should now look like this:


Step 4: Save and Exit

Save the file and exit the text editor.

Step 5: Update GRUB

Finally, run the following command in the terminal:

sudo update-grub

This command updates the GRUB configuration based on the changes you made in the file.

After completing these steps, restart your PC. The GRUB menu should now appear on every boot, allowing you to choose between Ubuntu and Windows.

Solution 2: Use EasyBCD on Windows

If you’re unable to resolve the issue with the first method, you can try using EasyBCD, a software that helps manage boot options.

Step 1: Boot into Windows

First, boot your PC into Windows.

Step 2: Install EasyBCD

Download and install EasyBCD from the official website.

Step 3: Add New Entry

Launch EasyBCD and go to the “Add New Entry” section. Here, select “Linux/BSD” from the operating systems list and choose “GRUB 2” as the type.

Step 4: Name the Entry and Select Partition

Enter a name for the entry (for example, Ubuntu) and select the partition where Ubuntu is installed.

Step 5: Add Entry and Restart

Click “Add Entry” to add the Ubuntu entry to the boot menu. After this, restart your computer. The GRUB menu should now appear, allowing you to choose between Ubuntu and Windows.

Solution 3: Use a Bootable USB with Boot-Repair

If the above solutions don’t work, you can use a bootable USB drive with the boot-repair utility.

Step 1: Create a Bootable USB Drive

You can create a bootable USB drive with the boot-repair utility using a tool like unetbootin.

Step 2: Boot from USB Drive

Boot your computer from the USB drive.

Step 3: Follow Boot-Repair Instructions

Follow the instructions provided by boot-repair to repair the boot configuration.

Step 4: Restart Your Computer

After the repair is complete, restart your computer. The GRUB menu should now appear, allowing you to choose between Ubuntu and Windows.

Please note, you should be cautious when using boot-repair as it may cause further issues if not used correctly.

By following these solutions, you should be able to fix the issue of your PC booting directly into Ubuntu without showing the GRUB menu. Remember, always back up your data before making changes to your system configurations. Good luck!
