Problem
After adding a SSD persistent drive to a custom machine image, it was found that the reconfigured VM would not boot as expected. The same image would boot without issue when SSD drives were not attached to the image. The following messages were identified in the Serial Console for the VM in question.

Environment
- Google Compute Engine
- RHEL 8.4 Custom Image
- Other versions and distributions might be affected, but haven't been tested.
Solution
Install the UEFI bootloader on the impacted image and re-deploy the virtual machine. For additional details on re-installing the bootloader please check this Red Hat Article.
Additional non Red Hat resource to install the bootloader can be found using some external documentation. See this post as an example.
Once the Boot Loader has been reinstalled and includes the EFI Boot Loader, copy the image to your cloud storage and import it back into your project. This allows you to create new instances with the new image and add local SSD drives to them. Please remember, once you are able to successfully boot the VM with the local SSD you will need to format the SSD drive before you can use it.
