booting issue

[Akai]

Hello, I have an issue with booting the image.

Quick background information: I received several laptops for testing, 2 Lenovos with AMD CPUs and 1 Lenovo with an Intel CPU. The details are in the attachment .

Now, onto my problem. After opening the iVentoy menu and selecting an image, the process gets stuck. I only see "preparing for boot, please wait."
This phenomenon only occurs with the AMD laptops, the Intel device works fine. The BIOS settings are identical.


In the log, there's nothing unusual, except that it eventually times out.

Additionally, I have an HP laptop with an AMD CPU where the iVentoy system works perfectly fine.

I hope you can help me and If you need more information, please let me know.
