Dual booting is an intriguing technique that allows you to install multiple operating systems on your computer. However, due to the fast startup feature or corrupt system files, the dual boot option can sometimes go missing.
If the dual boot option is missing on your computer, you’ve come to the right place. We’ll explore five quick ways to fix the dual boot option not showing on Windows 11. So, let’s begin.
1. Enable Dual Boot Option Using Command Prompt
Sometimes, the dual boot option goes missing on upgrading the operating system. When that happens, you can re-enable the dual boot option using Command Prompt. Follow these steps to do that:
Step 1: Press the Windows key to open the Start Menu.
Step 2: Type Command Prompt and choose Run as administrator.
Step 3: Type the following command and press Enter.
bcdedit /set {bootmgr} displaybootmenu yes
After you execute this code, you’ll see the ‘Operation completed successfully’ message. After that, check if the problem continues.
2. Turn Off Fast Startup
Fast Startup is an incredible feature in Windows that facilitates quick computer restarts after shutdown. This feature proves especially useful if your computer takes a long time to restart.
However, the dual boot feature blocks the Windows installation drive, leading to the operating system’s failure to recognize the dual boot system. In such cases, the solution is to disable the fast startup option on your computer.
Step 1: Press the Windows key to open the Start Menu, type Control Panel in the search bar, and press Enter.
Step 2: Choose System and Security.
Step 3: Select Power Options.
Step 4: Click the ‘Choose what the power button does’ option in the left sidebar.
Step 5: Click the ‘Change settings that are currently unavailable’ option.
Step 6: Uncheck the ‘Turn on fast startup’ box. Then, click the Save changes button.
After that, restart your computer and check if the dual boot option appears.
3. Choose the Default Operating System in Startup and Recovery
Another quick way to fix the dual boot option not showing on Windows 11 is to configure the default operating system on your computer. Here’s how to do that:
Step 1: Press the Windows + I keyboard shortcut to launch the Settings app.
Step 2: Choose System from the left sidebar and click the About option in the right pane.
Step 3: Click the ‘Advanced system settings’ option in the right pane.
Step 4: In the Advanced tab, click the Settings button under ‘Startup and Recovery’.
Step 5: Select the default OS from the ‘Default operating system’ drop-down menu. Then, click the OK button.
Next, check if the problem persists. If yes, try the next solution on the list.
4. Enable Boot Disk Partition
To use the second operating system installed on a disk partition, it’s important to enable the partition for the computer to boot from it. If you fail to enable it, the dual boot option will not appear. You can enable the boot disk partition by following the below steps:
Step 1: Press the Windows key to launch the Start Menu, type Command Prompt in the search bar and choose Run as administrator from the right pane.
Step 2: Type diskpart into the Command Prompt window and press Enter.
Step 3: Type list disk and press Enter. This will list all the disks on your computer.
Step 4: Type select disk (DiskNumber) and press Enter. Make sure to replace DiskNumber with the actual number of the disk where you’ve installed the second OS.
Step 5: Type list partition and press Enter. This will give a list of all the partitions on the selected disk.
Step 6: To choose the target partition, type select partition (PartitionNumber). Make sure to replace PartitionNumber with the actual number of the target partition.
Step 7: Type Active and press. This will enable the selected partition.
You will see the ‘DiskPart marked the current partition as active’ message when the process completes.
5. Run SFC and DISM Scan
If the dual boot option is still missing, you can run SFC (System File Checker) and DISM (Deployment Image Servicing and Management) scans. Running these scans will detect and replace corrupt system files that might be causing the issue. Here’s how to run these scans:
Step 1: Press the Windows key to launch the Start Menu, type Command Prompt in the search bar and click the ‘Run as administrator’ option in the right pane.
Step 2: Type sfc /scannow and press Enter. This will run SFC scan on your computer.
Step 3: Type the following commands one by one and press Enter after each command:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
After the scanning process is complete, restart your computer, and you’ll see the dual boot option.
