Windows 11 does not boot after partition restore on same disk (switching from Linux to Windows)

[odroid]

Hello,

I am using R-Drive Image on a 512GB SSD configured with GPT/UEFI.

My disk setup contains:

One Linux installation

One separate Windows 11 installation

One 300GB NTFS partition used only for personal data

Important: I do NOT want the 300GB data partition to be deleted during restore.

Here is my workflow:

I regularly switch between operating systems.

For example, if I am currently using Linux and I decide to switch back to Windows:

I delete the Linux partitions.

This creates unallocated space on the same SSD.

I then restore the Windows backup partitions into that unallocated space.

I restore all Windows-related partitions in the same original order (EFI, MSR, Windows, Recovery, etc.).

I do NOT restore the entire disk — only the Windows partitions.

The restore process completes without errors.

However, Windows 11 does NOT boot after this partition-by-partition restore.

If instead I perform a full disk restore, Windows boots correctly — but this deletes my 300GB data partition, which I want to keep.

When Windows does not boot after the partition restore, I must repair the bootloader manually by:

Booting from a Windows 11 installation USB stick.

Opening Command Prompt from the recovery environment.

Running:

bcdboot C:\Windows /l fr-fr /s S: /f UEFI

After running this command, Windows boots normally again.

So my questions are:

Why does Windows 11 fail to boot when restoring only the Windows partitions on the same disk, even though they are restored in the original order?

Does R-Drive modify disk or partition GUIDs during partition restore?

Is there a way to restore Windows so that:

It boots correctly

The 300GB NTFS data partition remains untouched

I do not need to perform a full disk restore?

The hardware and SSD remain exactly the same. I am not migrating to another disk.

Linux partition restores work perfectly in the same scenario, but Windows requires either a full disk restore or manual BCD repair to boot properly.

Any clarification or recommended restore settings would be greatly appreciated.

Thank you.
