  !!! Info "Cloud-native"
 
-  In case you want to be more cloud-native, you can select the "Boot from image (creates a new volume)" option. This option creates a new persistent volume for your instance. In the event you accidentally delete your instance or it enters an unrecoverable state, the file system of your instance will be saved in this volume. You can later use this volume to boot up a new instance with the same filesystem state as the previous instance.

You can later use this volume to boot up a new instance with the same filesystem state as the previous instance.
 
  !!! Warning "Please note"
 
-  The "Boot from image (creates a new volume)" approach creates an additional volume which is billed normally as mentioned on our [pricing](https://research.csc.fi/billing-units) page.
+  The option "Create New Volume" set to "Yes" creates an additional volume which is billed normally as mentioned on our [pricing](https://research.csc.fi/billing-units) page.
 
+  If the flavour type has an ephemeral disk (for example, [I/O flavours](./vm-flavors-and-billing.md#io-flavors)), a new volume is only created for the root disk. [Ephemeral disks](./ephemeral-storage.md) are removed when the VM is deleted.
 
-1. **Image Name**, this decides which Linux distribution to use. You can select the image that fits more your use case. The images provided by Pouta by default are regularly maintained up to date.
 
-1. Under the **Access & Security** tab, you need to configure two options. First you need to choose the name of the *Key Pair* you have created in [**Setting up SSH keys**](#setting-up-ssh-keys). Secondly you need to select under the [**Security Groups**](#firewalls-and-security-groups) the security group previously created.
+1. Select the **Flavour**, which is the "size" of the Virtual Machine that you will create, from the available flavours and by clicking the up arrow. See [Virtual machine flavors and billing unit rates](vm-flavors-and-billing.md) for a complete list and descriptions. You can also expand the flavour to check the impact on your quota.
 
- !!! Warning "Key pairs cannot be added after creation"
- A public key is only added to the VM if it has been specified in this step. After clicking on **Launch**, the VM will be created, and the configured key pairs cannot be changed. If no key pair is configured, the recommended solution is to delete the VM and start from scratch.

+  Pay attention that you can have a warning sign indicating if your quota is sufficient to run a specific flavour. If your quota is not enough, you can send a request to our [Service Desk](mailto:servicedesk@csc.fi) by specifying the amount you want.
