Dear Anne. through the CD you listed to me, and the net, i got my debian 11.3. its good.
Excellent, so the multi-arch netinst CD is booting properly into the installer. Now you're trying to do a next step.
but i wanted to try again some way to get my debian directly by the 1st DVD. through USB i got the same problem as the DVD, just the same. so i tried inserting the CD and then replacing it with the DVD....... and you wrote: "Once the installer has started, you can put in an amd64 DVD to install software from." good: something happened, but i got this error: error: file '/install.amd/vmlinuz' not found error: you need to load th kernel first
This is expected; indeed you swapped too early.
so, i tried to continue with the CD again, inserting the DVD after the next step, but during the phase "detecting hardware to find installation media" a problem reading data was showed.
Okay, this should probably have worked, but I might have remembered incorrectly.
When you leave the CD inserted, and the installer detects and scans it, will that work properly? Now right after that, the installer should ask you if you have another disc to scan. At that question, you can take out the CD, insert the DVD, and *then* choose Yes (if I remember the sequence correctly). This way, the installer will register both the CD and the DVD, and can install software from both of them.
When the CD is scanned properly using this process, but the DVD fails, then your DVD is bad. Maybe the DVD has bad data on it (corrupted download), or the DVD burner is bad, or the DVD reader is bad. Then it's easiest to just forget about the DVD, and only use the CD, and have the rest of software downloaded from the internet by the installer. The installer will prompt you for network settings and a software download location ("mirror") for that purpose.
i would like to try clearing the first 512 bytes of the iso file, but i dont know the way to do that.
Now that you can start the installer from CD, you can forget about the first 512 bytes. It will not change detection of the DVD by the installer in any way.
