Hello
I am interpreting two users of a French forum who have the same problem. For one it is from the beginning.
This is still the case with the new version 0.20
(  https://forum.ubuntu-fr.org/viewtopic.ph...#p22330988 )

He say

Arrived at the command prompt (initramfs), I have this message:

Unable to find a media containing a live filesystem

For the command (it was indeed sdb2):

/ventoy/busybox/sh /ventoy/hook/debian/udev_disk_hook.sh sdb2

...I got:

/ventoy/busybox/sh: Can't open '/ventoy/hook/debian/udev_disk_hook.sh': no such file or directory

We see several * .sh scripts by checking the contents of the / ventoy / hook / debian directory, but none named udev_disk_hook.sh
This script does not appear to be included in Ventoy 1.0.20?

Can you say exactly what to do with the new version
Thank you

Good evening
"Ventoy version 1.0.21 released; still unable to launch my iso files on my machine in “legacy” BIOS, we still end up at the command prompt (initramfs).
On the other hand, the script udev_disk_hook.sh is present in this version and I was able to produce the file / ventoy / log"
