For convenience, I mainly test Ventoy on virtual machine with QEMU or VirtualBox. Also my old ThinkPad laptop is used sometimes.
However the bios firmware are different by vendor, even some has buggy in it.
So the iso file listed here may not work on you machine. Please let me known if you run into problems, you can mail to me or report an issue in the forums. I will do my best to fix it.
If you successfully test an ISO file which is not listed here, you can tell me and I will be very glad to add it here.
For krd.iso, grub signature check was enabled in UEFI mode by default. Ventoy must do some hook to avoid "kernel.dat not found" error, but the hook will be denied by the check.
So in UEFI mode, after the kaspersky boot menu was shown, you need to run
set check_signatures=no in the grub shell before boot.
