Invalid partition table

[TLINDEN]

bootiso: v4.1.1

unknown

Describe the bug

I created a usb boot stick with Kubuntu and tried to boot into it on a Dell XPS 13. It starts to read from the stick (led blinking) but dies very fast with Invalid partition table.

Expected behavior (for behavioral bugs only)

Boot into Kubuntu.

Reproduction

bootiso -d /dev/sdb kubuntu-23.10-desktop-amd64.iso -L KUBUNTU --mrsync

I also tried legacy boot mode with the same result.
