Are you using a UEFI-compatible image?

Information

There is two CentOS GenericCloud 9

• CentOS-Stream-GenericCloud-9-latest.x86_64.qcow2
• CentOS-Stream-GenericCloud-x86_64-9-latest.x86_64.qcow2

From What is the difference between these CentOS 9 Stream cloud images?.

They have two different kickstart (like seed file for debian installation);
One hasn't efi partition creation, the second has.

Solution

Replace CentOS-Stream-GenericCloud-9-latest.x86_64.qcow2
with CentOS-Stream-GenericCloud-x86_64-9-latest.x86_64.qcow2.

I don't understand. The guide just gives some examples of images that could be used. Are you saying that CentOS-Stream-GenericCloud-x86_64-9-latest.x86_64.qcow2 will work in more places than CentOS-Stream-GenericCloud-9-latest.x86_64.qcow2?

Since the hardware we used in the guide doesn't support UEFI, it is quite logical that the image we used also didn't support it. I think we can try to get the guide updated to use UEFI hardware, but just changing the image without changing the rest doesn't make sense to me.

Another option is also to list both images and explain which should be used in which case.

IDK, I didn't try on other type.
In my case, that solved my issue.

Make sense.

IMO, it's a great idea.
