# Configure Hypervisor For UEFI Instance Boot

## Problem

* Unified Extensible Firmware Interface (UEFI) is a standard firmware designed to replace legacy BIOS.
* By default, an instance boots in BIOS mode.

## Environment

* Platform9 Managed OpenStack - v3.6.0 and Higher
* Ubuntu 16.04
* CentOS 7.4 and Higher

## Procedure

1. Install OVMF

* Ubuntu

{% tabs %}
{% tab title="None" %}

```none
# openstack image set # apt install ovmf--property hw_firmware_type=uefi [image UUID]
```

{% endtab %}
{% endtabs %}

* Centos

{% tabs %}
{% tab title="C" %}

```c
# yum install OVMF -y

# cd /usr/share/OVMF && ln -s OVMF_CODE.secboot.fd OVMF_CODE.fd
```

{% endtab %}
{% endtabs %}

2. Add ***hw\_firmware\_type*** image metadata to the UEFI image to indicate the firmware type used to boot the instance.

{% tabs %}
{% tab title="None" %}

```none
# openstack image set --property hw_firmware_type=uefi [image UUID]
```

{% endtab %}
{% endtabs %}

3. Boot the instance using the UEFI image.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://platform9.com/kb/pmo/how-to/configure-hypervisor-for-uefi-instance-boot.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
