I have experience this ventoy issue several time, never know where to post to get help.

I have got a ventoy installed usb. There are several iso in it, some is bootable, some is not (example, supergrub2 hybrid & efi (one work, 1 does not), win7iso (not working), gparted (not not work), some linux distro iso (works good on ventoy).

When i changed my bio setting to use EFI instead of previously MBR; and tried to boot into some of the iso with ventoy , it become unbootable. Even after change back to MBr

I wanted to ask Ventoy, but their forum is not postable.
