# Deploying Edge Microvisor Toolkit on Bare Metal

In this article will learn how to deploy Edge Microvisor Toolkit on bare metal using ISO or
RAW images.

## Requirements

- OS image, depending on the version of Edge Microvisor Toolkit:
  - [ISO image of Developer Node 3.0](#installing-edge-microvisor-toolkit-developer-node)
  - [RAW image of Edge Microvisor Toolkit Standalone Node 3.0](#installing-edge-microvisor-toolkit-standalone-node)
- USB flash drive (min. 8GB)
- Access to the target machine
- Optional: monitor and keyboard, or BMC/iDRAC/iKVM access

## Creating Bootable USB

### Flashing ISO

Download the
[ISO image](https://files-rs.edgeorchestration.intel.com/files-edge-orch/microvisor/iso/EdgeMicrovisorToolkit-3.0.iso)
and insert a USB drive.

#### On Linux OS

1. Compare the output of `lsblk` before and after inserting your USB drive to identify
its name (for example, `/dev/sdb`).

   ```bash
   lsblk
   ```

2. Flash the ISO Image. Use the `dd` command to write the ISO image.
Replace `/path/to/your.iso` with the ISO’s location and `/dev/sdb` with your USB drive.

   ```bash
   sudo dd if=/path/to/your.iso of=/dev/sdb bs=4M status=progress oflag=sync
   # Warning: Double-check the drive name. Using a wrong drive can overwrite data.
   ```

3. Sync and eject: Once `dd` has finished, run:

   ```bash
   sudo sync
   ```

   Then, safely remove the USB drive.

#### On Windows OS

Download and install ISO writer software such as [Rufus](https://rufus.ie/en) or
[Balena Etcher](https://etcher.balena.io/). The latter simplifies the process
to just selecting ISO image and target USB drive.

##### Rufus workflow

If you decide to use Rufus, follow
the instructions below:

1. Insert the USB drive (8GB or more).
2. Launch Rufus.
3. Select the USB drive from the dropdown list.
4. Boot selection: Select your EMT 3.0 ISO file.
5. Image option: Leave default or choose *Standard Installation*.
6. Partition scheme: MBR (for legacy BIOS) or GPT (for UEFI).
7. File system: FAT32 (recommended).
8. Click *Start*.
9. Confirm warnings about data being erased.
10. Wait for completion and safely eject the USB.

Next, set up the target machine to [boot from the USB drive](#booting-from-usb) to
[install Edge Microvisor Toolkit Developer Node](#installing-edge-microvisor-toolkit-developer-node).

### Flashing RAW

You can [Build](../emt-building-howto.md#build-the-edge-microvisor-toolkit-image) a RAW image
and flash it on a USB drive.

1. Navigate to the folder with the RAW image. Then, unpack the image by running the commands:

   ```bash
   gzip -d edge_microvisor_toolkit.raw.gz
   chmod -Rf 777 edge_microvisor_toolkit.raw
   ```

2. Flash the RAW image to a USB flash drive using the 'dd' command.

   ```bash
   sudo dd if=edge_microvisor_toolkit.raw of=/dev/sdc status=progress
   ```

   > **Note:** Successful flashing of the image should produce partitions such as `/dev/sdb`
     and `/dev/sdc`.

### Booting from USB

1. Insert the USB into the target machine.
2. Enter the BIOS/Boot menu.
3. Choose the USB drive as the boot device.

## Installing Edge Microvisor Toolkit Developer Node

1. Choose *Terminal Installer* or *Graphical Installer* when prompted

   ![Select installer](../../assets/01-select-installer.png)

   **Follow Installation Prompts**

2. Choose the installation type:

   ![Installation type](../../assets/02-installation-type.png).

3. Select the target disk for installation and choose the partitioning method.

   ![Partition](../../assets/03-partition-config.png).

4. Skip disk encryption (optional).
5. Create a username and a password. Keep the default *Hostname*.

   ![System config](../../assets/04-system-config.png).

6. Click *Install* and confirm by clicking *Install Now*.

7. When the installation has completed, click *Done* to close the installer.

   ![Complete](../../assets/05-install-complete.png).

   The system will reboot.

   **You are now ready to use Edge Microvisor Toolkit!**

8. (Optional) Check the version of Edge Microvisor Toolkit by running the following command:

   ```bash
   cat /etc/os-release
   ```

## Installing Edge Microvisor Toolkit Standalone Node

Build the OS image and prepare a bootable USB drive, using
[source code](https://github.com/open-edge-platform/edge-microvisor-toolkit-standalone-node/blob/main/standalone-node/docs/user-guide/Get-Started-Guide.md#prerequisites) to deploy a selected version of the standalone node.

Edge Microvisor Toolkit Standalone Node can be installed from one of available OS
image versions:

- Edge Microvisor Toolkit Non-RT (default)
- Edge Microvisor Toolkit RT (real-time)
- Edge Microvisor Toolkit Desktop Virtualization
