Windows 11 dual boot install error

Hello, Jakub I

Welcome to the Microsoft community.

Thank you for your feedback. I understand that you are experiencing a failed dual system installation of Windows 11 with Manjaro, here are some troubleshooting options:

1. Backup data: Ensure that the data on both the Manjaro and Windows target disks have been backed up.

Download the tool:

Make a Windows 11 installation USB flash drive in UEFI mode using Rufus or Ventoy.

Prepare Manjaro Live USB for GRUB repair at a later stage.

2. Adjust BIOS/UEFI settings

Reboot into BIOS (press Del/F2/F12 on boot).

Ensure the following options are enabled:

UEFI mode (Legacy/CSM disabled).

Secure Boot → Set to Windows UEFI or other OS.

TPM 2.0 → Enable.

Save and exit.

3. Physically isolate the Manjaro drive (critical step)

Disconnect the power or data cable of the 500GB NVMe drive where the Manjaro is located after shutdown.

Avoid the Windows installation program from accidentally writing the boot partition.

Leave only the 1TB target drive connected.

4. Install Windows 11 to 1TB hard disk

Insert the Windows 11 installation USB flash drive and boot.

After entering the installation interface, press Shift + F10 to open a command prompt and execute the following command to clean the target disk:

diskpart

list disk

select disk 1

clean

convert gpt

exit

Return to the installation interface → Select Unallocated Space → Next to automatically create the required partition.

Finish the installation and go to the desktop.

5. Repair Dual System Boot (after reconnecting the Manjaro drive)

Reconnect the 500GB NVMe drive after shutting down the computer.

Boot with Manjaro Live USB → Enter the Live environment.

Mount the Manjaro root partition and repair GRUB:

sudo su

mount /dev/nvme0n1pX /mnt # X is replaced with Manjaro root partition number

mount /dev/nvme0n1pY /mnt/boot/efi # Y is replaced with EFI partition number

arch-chroot /mnt

grub- install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Manjaro

grub-mkconfig -o /boot/grub/grub.cfg

exit

reboot

reboot should see the The GRUB menu contains Windows and Manjaro options.

6. Integrate missing drivers to the installation media (optional)

If you encounter driver problems during installation (e.g. network drivers):

Download the drivers from another PC (get Windows 11 x64 drivers from the motherboard/laptop official website).

Use a tool to inject the driver into the Windows image:

Recommended tool: DISM++ or manual command:

dism /Mount-Image /ImageFile:install.wim /Index:1 /MountDir:mount

dism /Image:mount /Add-Driver / Driver:Driver Folder /Recurse

dism /Unmount-Image /MountDir:mount /Commit

Common Error Handling

Error Code 0x80070002/0x8007000D:

Re-make the installation USB flash drive (use the official image + Rufus to select GPT+UEFI mode).

Unable to recognize NVMe HDD:

Enable NVMe controller in BIOS or update motherboard firmware.

Can't get into Windows after installation:

Install USB drive with Windows → Repair boot → Execute bootrec /rebuildbcd.

Ultimate solution

If it still fails, reinstall in this order:

Disconnect Manjaro drive → Install Windows 11.

Connect Manjaro drive → Reinstall GRUB.

If GRUB doesn't recognize Windows, execute in Manjaro If GRUB does not recognize Windows, in Manjaro do:

sudo os-prober

sudo update-grub

If you still have problems, it is recommended to check the hardware (e.g. the health of the hard disk) or try to change the installation media.

I look forward to your feedback.
