In this article, we will guide you through the process of fixing the Grub menu that’s not showing after upgrading to Windows 10 in a dual boot system. This is a common issue that many users encounter when they upgrade their Windows system while running a dual boot setup with Linux.
To fix the Grub menu not showing after upgrading to Windows 10 in a dual boot system, you can try disabling the Fast Startup feature in Windows 10, using the Boot Repair tool in Ubuntu, or changing the boot order in your system’s BIOS.
Understanding the Issue
The Grub (Grand Unified Bootloader) is a bootloader package developed to support multiple operating systems and allow the user to select among them during boot-up. It’s widely used and is the default bootloader for many Linux distributions. However, when you upgrade your Windows system, it might override the Grub, causing it not to show at the boot time.
Solution 1: Disable Fast Startup in Windows 10
The first solution we recommend is disabling the Fast Startup feature in Windows 10. This feature is designed to help your system boot faster, but it can cause problems with dual boot systems.
Step 1: Boot into your Windows 10 system.
Step 2: Go to the Control Panel.
Step 3: Select ‘Power Options’.
Step 4: On the left-hand side, click on ‘Choose what the power button does’.
Step 5: Click on ‘Change settings that are currently unavailable’.
Step 6: Under ‘Shutdown settings’, uncheck the ‘Turn on fast startup’ option.
Step 7: Save changes and reboot your system.
Solution 2: Use Boot Repair in Ubuntu
If disabling Fast Startup doesn’t solve the issue, you can use the Boot Repair tool in Ubuntu.
Step 1: Boot into Ubuntu using a live boot.
Step 2: Open the terminal.
Step 3: Type the following commands one by one:
sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install -y boot-repair && boot-repair
The first command adds the Boot Repair software to your list of repositories. The second command updates your system, and the third command installs Boot Repair and launches it.
Step 4: Once Boot Repair is open, click on ‘Recommended repair’. This will repair most common issues.
Step 5: Reboot your system.
Solution 3: Change the Boot Order in BIOS
If the above solutions don’t solve the issue, you can try changing the boot order in your system’s BIOS settings.
Step 1: Boot into the BIOS menu. This is usually done by pressing F10, F12, or another key during boot-up. The key varies depending on the system manufacturer.
Step 2: Find the booting device menu.
Step 3: Ensure that the Ubuntu Boot Manager is listed above the Windows Boot Manager. If it’s not, use the arrow keys to change the order.
Step 4: Save the changes and exit the BIOS.
Remember to back up any important data before making any changes to your system. If you’re not comfortable making these changes, consider seeking help from a professional.
In conclusion, while upgrading to Windows 10 in a dual boot system can cause issues with the Grub menu, these can usually be resolved by disabling Fast Startup, using Boot Repair in Ubuntu, or changing the boot order in BIOS.
Fast Startup is a feature in Windows 10 that allows the system to boot up faster by saving some system information to a hibernation file. When enabled, it can cause issues with dual boot systems, including the Grub menu not showing.
To check if Fast Startup is enabled, go to the Control Panel, select ‘Power Options’, click on ‘Choose what the power button does’, and then click on ‘Change settings that are currently unavailable’. If the ‘Turn on fast startup’ option is checked, it means Fast Startup is enabled.
Yes, you can re-enable Fast Startup after fixing the Grub menu issue. However, it’s recommended to keep it disabled if you want to avoid any potential conflicts with dual boot systems.
Yes, you can use Boot Repair even if you have a different Linux distribution installed. Boot Repair is a widely used tool that can help fix bootloader issues in various Linux distributions.
No, using Boot Repair should not delete any of your data. However, it’s always a good practice to back up your important data before making any changes to your system, just in case.
If none of the solutions mentioned in the article work for you, it’s recommended to seek help from a professional or consult the support forums of your specific Linux distribution for further assistance. They may be able to provide more specific guidance based on your system configuration.
