PC will not load Ventoy

[KaMyKaSii]

I am having the same issue too. I can not boot both from a PC with legacy BIOS and from a couple of PCs with UEFI (secure boot disabled).
I also tried the the way suggested by KaMyKaSii without any luck.
I prepared the usb from Windows using the .exe file.

Did you try the new Ventoy update? With it my pc booted Ventoy while using Legacy boot for the first time
