How To Fix Read-Only Partition Issue in Dual Boot Win10 and Ubuntu

Ubuntu 8

If you’re running a dual boot system with Windows 10 and Ubuntu, you may encounter a common issue where the data partition in Ubuntu is read-only. This can be frustrating, but there are several ways to resolve this issue. In this article, we’ll guide you through the steps to fix this problem.

Understanding the Issue

The read-only partition issue often arises due to Windows 10’s Fast Startup feature or when Windows is hibernated. These features can prevent Ubuntu from accessing the data partition correctly, resulting in a read-only message.

Solution 1: Disable Fast Startup

Fast Startup is a feature in Windows 10 designed to reduce boot time by pre-loading some boot information before your PC shuts off. While this feature can be useful, it can cause problems when dual booting with Ubuntu.

To disable Fast Startup:

  1. Boot into your Windows 10 system.
  2. Navigate to the Control Panel.
  3. Click on “Hardware and Sound”.
  4. Click on “Power Options”.
  5. On the left-hand side, click on “Choose what the power buttons do”.
  6. Click on “Change settings that are currently unavailable”.
  7. Under “Shutdown settings”, uncheck the box that says “Turn on fast startup”.
  8. Click on “Save changes”.

After disabling Fast Startup, perform a proper shutdown in Windows before booting into Ubuntu. You should now be able to access the data partition with read/write permissions.

Solution 2: Check Hibernation Status

If Windows is in a hibernated state, Ubuntu will only be able to access the data partition in a read-only mode. To ensure that Windows is not hibernated, you can perform a full shutdown.

To do this, open a command prompt in Windows (press Win + X, then select Command Prompt) and type the following command:

shutdown /s

This command will perform a full shutdown of your system. The /s switch indicates that the system should be shut down.

Solution 3: Disable Hibernation

If the issue persists, you may need to disable hibernation in Windows. To do this, open a command prompt as an administrator and enter the following command:

powercfg.exe /hibernate off

This command disables hibernation by toggling the ‘hibernate’ setting off. After this, make sure to disable Fast Startup in the power options as described in Solution 1.

Solution 4: Check Group Policy Restrictions

In some cases, the “Disable Fastboot” option may be restricted by group policy settings. If you find that you’re unable to change this setting, you may need to consult with your system administrator or look for alternative solutions.

Conclusion

While the read-only partition issue can be a nuisance when dual booting Windows 10 and Ubuntu, it can usually be resolved by disabling Fast Startup or hibernation in Windows. However, it’s important to note that forcing read/write permissions for a hibernated Windows partition is not recommended, as it can lead to data corruption. Always ensure that Windows is properly shut down before accessing the data partition in Ubuntu.

By following the steps outlined in this article, you should be able to effectively resolve the read-only partition issue and enjoy the full benefits of your dual boot system.

Why is the data partition in Ubuntu read-only when dual booting with Windows 10?
