Amazon EC2 now supports Unified Extensible Firmware Interface (UEFI) boot when migrating virtual machines from on-premise to EC2 without having to convert them to Legacy BIOS. UEFI is a modern firmware that initializes your operating system.
Previously, virtual machines that were migrated to EC2 needed to be converted from UEFI to Legacy BIOS. Now, you can use migration services like CloudEndure Migration, offered by AWS, and continue using UEFI on your EC2 instances.
UEFI boot is supported on the majority of Intel- and AMD-based EC2 instance types built on the AWS Nitro System. UEFI boot is available in all public AWS Regions and AWS GovCloud (US).
To learn more about using UEFI boot, please visit the
UEFI boot documentation. For more information on migrating UEFI based VMs using CloudEndure Migration, refer to the
CloudEndure documentation.
