Solved Two boot menus BIOS and UEFI

[nguyen ha thai trong]

All of them work for both. Only one doesn't, so I would need duplication for all the others which is a waste of space and something I want to avoid. I set that one  iso to VTMEMDISK which gives me a grub message when trying to boot it that says it's for UEFI only before returning to the Ventoy menu. I can live with that.

When booting your iso directly using QEMU tester in Legacy bios mode, does it boot ok?
