I’m using Ventoy on a USB flash drive and I’m trying to boot
haiku-r1beta3-x86_64-anyboot.iso from it on an Lenovo X220. I chose the Haiku iso from the Ventoy menu and then I only get a blinking white underscore (?) in the upper left corner. Nothing happens, I’ve waited 30 minutes and tried a few times.
I have other OS that boots fine from the same flash drive on the same machine.
