The user is experiencing duplicated or split folders in OneDrive when running a dual-boot setup with Windows 10 and Windows 11.

How to Fix OneDrive Folder Duplication in a Dual-Boot Windows Setup

Product: Microsoft OneDrive
Device & OS: Windows 10 and Windows 11
Scenario: Using Microsoft 365 and synchronizing local files to OneDrive from two different Windows operating systems installed on the same machine.
Observed behavior: OneDrive creates duplicate copies of folders or splits them because both operating systems are attempting to synchronize the same local directories independently.

Before you start

Ensure you have paused OneDrive syncing on both operating systems and backed up any critical files to an external offline drive to prevent accidental data loss during reconfiguration.

Solution 1Recommended

Configure a Single Active Sync Configuration

Prevent folder duplication by ensuring only one operating system actively manages the core OneDrive backup and sync for your shared local files.

When two separate Windows installations try to upload and sync the same local folders simultaneously, OneDrive often creates duplicated folders appended with the computer name to avoid overwriting data. Restricting sync to one primary OS resolves this.

Boot into the primary OS

Start your computer and boot into your primary Windows operating system (e.g., Windows 11) where you want OneDrive to actively manage your files.

Allow initial sync to complete

Open OneDrive from the system tray and wait for the status to show 'Up to date'. Ensure all manual uploads and Microsoft 365 documents have fully synchronized to the cloud.

Boot into the secondary OS

Restart your computer and boot into your secondary Windows operating system (e.g., Windows 10).

Disable overlapping folder backups

Click the OneDrive icon in the system tray, go to Settings > Sync and backup > Manage backup. Turn off the backup toggles for Desktop, Documents, and Pictures to prevent this OS from duplicating the sync process.

Configure a Single Active Sync Configuration

Synchronization Verified: By offloading the backup responsibility to a single OS, you maintain cloud access to your files without triggering OneDrive's duplication failsafe.

Solution 2

Change Default Save Locations in Microsoft 365

Stop Microsoft 365 applications on your secondary OS from automatically uploading local documents to OneDrive.

Frequently Asked Questions

Why does Microsoft 365 default to saving in OneDrive?

Microsoft 365 sets OneDrive as the default save location to ensure files are backed up and accessible across all your devices. However, in a dual-boot setup, this default behavior can cause synchronization conflicts if both operating systems are actively managing the same local folders.

Can I point both Windows 10 and Windows 11 OneDrive clients to the exact same local folder?

It is highly discouraged. When two distinct OneDrive clients monitor the same local directory, they fail to recognize each other's sync cache. This causes the clients to view the files as new or conflicting, resulting in duplicate files and folders appended with your computer's name.

How do I know if my initial OneDrive upload is complete before switching operating systems?

You can verify the sync status by clicking the OneDrive cloud icon in your Windows system tray. If it displays a solid cloud icon without circular arrows, and the status reads 'Your files are synced', the initial upload is fully complete.
