AWS Windows 2019/2022 - Booting from Hard Disk 0

Packer
1

Hi, I’m creating Windows AMIs on AWS using Packer v1.14.3.

I’ve successfully built a Windows Server 2016 image. Using the same Packer configuration, I’m now trying Windows Server 2019 (and also tested Windows Server 2022).

The build starts fine: the instance launches, Packer connects over WinRM, and provisioning begins. However, after the first reboot, the instance never comes back up. In the AWS console I only see: Booting from Hard Disk 0…
Packer eventually times out waiting for WinRM.

Has anyone seen this behavior with Windows 2019/2022 on AWS using Packer 1.14.3, or have suggestions on what to check?

Any pointers appreciated.

This is resolved. MBR2PGT was ran higher in the code ad converted the disk to GPT.
