Summary0000430: AWS AMI support for the UEFI
DescriptionIn AWS using the AlmaLinux image I'm not able to boot the instance as an UEFI.

If the OS is ready to be booted as an UEFI, the issue can be caused by the fact that the boot method for the AMI instance is not set:

There is missing "BootMode". Can you please add it to make the alma UEFI ready? Set the BootMode to "uefi-preferred".

Hi mlitwora,

We are testing 8.9-beta-1 and 9.3-beta-1 AMIs in the "uefi-preferred" boot mode. Which basically means an instance will be created and boot in UEFI if it's supported by the instance type.

Would you like to help us with the testing?

Here is the AMI IDs on the us-east-1 region. You can also copy them to another region if you want.

AlmaLinux OS 8.9-beta-1.20231107 x86_64: ami-0ebb096e453d2fb20
AlmaLinux OS 9.3-beta-1.20231107 x86_64: ami-04036e2559f9d72d9

Hi elkhan,
sorry for late reply. We already noticed the added uefi option in AWS for the AlmaLinux images. Thanks for working on this issue!
