It can't communicate with the kernel when it's trying to create a partition over one that is already in use.

I have Windows 11 on a Lenovo, and downloaded the iso from omarchy.org on Oct. 8, 2025.

Because the iso uses the entire device

you probably had windows on the same device

Thank you for replying. Yes that was the problem I actually needed two discs just like the instructions said but seems subtle and I ignored it but I fixed it now and it works.

I used a WSL app that can talk to USB devices and then I used Ubuntu 2404. From there I did a mkfs ext4. And the hard part for me was that both of my discs were from SanDisk
