unable to boot certain ISOs without legacy support

[herpsn]

Hi, 

I just tested Ventoy a little bit. Really great tool.

Here are the ISOs i tested with my lenovo yoga 720-15:

only works with legacy support: ElementaryOS, LinuxMint, Ubuntu, KDE NEON

works with EFI and Legacy Support: Arch Linux, EndeavourOS; MX-Linux, Deepin Linux, Manjaro, Windows10

attached are the screenshots of the debug output from Elementary OS and Linux Mint when the ISO is not booting in EFI. Maybe this can help in solving the booting only in legacy support for certain ISOs.

Please checksum the ISO files in Ventoy's menu as follows to make sure that the ISO files are not corrupted.

Take Ubuntu for example, did it hang at the end? or any error message? Any screenshot?

Are you using a USB 3 port and a USB 3 device?
If so, try using a USB 2 port or connect the USB drive using a USb 2 extension cable.
Try a different SUb device - preferably USB 2.
