Description

As suggested by @favogt, the .xml file can be used from a mounted drive instead of modifying the whole ISO. This would simplify the process a lot, as there won't be need to edit the ISO file every time a new version is released.

mkisofs -J -graft-points -o autounattend_uefi.iso Autounattend.xml=Autounattend_UEFI.xml

Take into account that the language of the downloaded ISO has to match the one specified in the xml file. In our case it should be en-US, not international en-GB.

There are plenty of issues trying to address more than two CDROM in scsi format, so I'm trying to use the two usual disks used for Windows ISO and VirtIO drivers, and then add a third one with a autounattend_<bios/uefi>.raw image.

There's no way of making this work by now. I'd focus on fixing the current installation for 24H2 as stated in #176097 and then I'd come back to improving this process.

Why? The HDD_2=autounattend_bios.raw HDDMODEL_2=usb-storage,removable=true NUMDISKS=2 works fine here.
