It's 5 CDROM drives in 5 bays, meaning all the SATA ports on the motherboard, the hard drive is a old M2 drive not a modern M2 PCIe sorry for my lack of information, I'm not an expert and my English isn't the best.
I also want to explain my process, I always have in the bays an emergency Debian Live disk, an emergency Alpine disk, one of the current installation disk and one of what I want to test which was Debian 13 in this case. I've now noticed that this error only occurs if there are multiple Debian disks in the bays at the same time. I just put other non-Debian disks and they worked perfectly. I think that while it's not a bug, this information should be included in the manual and release notes. Cheeers
