Not missing anything. Won't boot in a VM for me neither. The image fails to write to a USB with Balena/Rufus too.
fyi @lukechilds @mayankchhabra

Can't get the iso to work on just regular PC. Balena writes .iso successfully but doesn't boot, Rufus says ISO image extraction failure at somewhere around 95% as indicated by attached picture

Yup exact same experience with Rufus. Balena fails to write for me too.

Yup exact same experience with Rufus. Balena fails to write for me too.

Balena only failed for me when I inadvertently tried to write the compressed file (.iso.xz) instead of uncompressing and trying with the resulting .iso file. Did you try both latest and 1.22 image files? Not sure if the versions are different but the file sizes are.

https://download.umbrel.com/1.2.2/umbrelos-amd64-usb-installer.iso https://download.umbrel.com/release/latest/umbrelos-amd64-usb-installer.iso.xz

Edit: I've tried both with balena and Rufus. Same results.

Can confirm the same under proxmox, using both the 1.2.2 and latest isos.

Currently, the umbrelOS iso doesn't support arm64 architecture. See issue https://github.com/getumbrel/umbrel/issues/1995. So, I think you are facing the same issue.

Are you trying to boot in an arm64 device?

I was able to install without issue using the ISO downloaded from latest release on github.

Check the EFI mode is enabled and the chipset is not emulating something very old. I was unable to get the ISO to boot with i440fx machine type but q35 had no issues.

Same issue here. Won't boot in a proxmox vm with an efi drive. not arm btw.

Ok solved it. press esc to enter biod and disable secure boot then the iso boots no problem.

Still Works. September 2025: Setup an UEFi and Q35 Linux VM. To boot directly from the "USB-Install.ISO" you need to disable secure boot in proxmox before booting (hit escape on booting in VMs console, Device settings and disable SecureBoot).
