Note:
Since February 2025 installation using Ventoy is deemed to work without any workaround.
Copy your desired OMLx .iso file to the Ventoy partiton on the Ventoy flash drive.
Boot that.
- Open Konsole (terminal) and
cd /run/initramfs/omdv/LiveOS - type
lsand check thatsquashfs.imgis present - Leave Konsole (terminal) open in that directory
- Open OMLx Calamares installer and install your new system
It seems as long as that directory is open and ls shows squashfs.img is present then user will be able to install their desired OMLx system booted from the Ventoy flash drive.
