Cant´t load some ISOs

[Steve2926]

Ventoy does not always work under VBox with some payloads. I don't know why. I rarely get any problems with other menu systems based on grub2\grub4dos\syslinux\isolinux, just Ventoy gives problems.
Same HBCDPE ISO UEFI-boots OK with grubfm under VBOX.
With Ventoy, if it doesn't work under VBox you always have to then test on real system.
