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 that supports UEFI, 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 Amazon Web Services Nitro System. UEFI boot is available in the Amazon Web Services China (Beijing) region, operated by Sinnet and in the Amazon Web Services China (Ningxia) region, operated by NWCD.
To learn more about using UEFI boot, please visit the UEFI boot documentation.
