Windows ISO create error

Thanks for the reply. You are correct. From a linux desktop the iso is directly available. (win7 and 10 prompt for the tool download only).

In case anyone is interested I got the ‘esd’ iso to install, without distrobuilder, by following default procedure, with the unmodified windows iso

Then added the virt-driver iso as an ide disk by a raw.qemu command similar to here

lxc config edit vm-2
added under
config:
raw.apparmor: /mnt/fs-0/** rwk,
raw.qemu: -drive file=/mnt/fs-0/virtio-win-0.1.185.iso,index=1,media=cdrom,if=ide

Changin wherever the iso is installated and appropriate file permissions.

And then starting the vm; selecting the scsi virtio driver on install etc.
