Unable to use Ventoy EFI files on my own partition

[parkerlreed]

I created a Ventoy USB stick and it worked great.



I wanted to replicate the setup on my pre-existing portable USB drive and am hitting a weird issue.

EFI/BOOT/bootx64.efi I copied to the EFI/BOOT/ folder

grub, tool and ventoy folders from the root of ESP I copied as well.

When I load bootx64.efi it ignores the grub.cfg and drops straight to grub console



Then when I load the cfg manually, the screen resizes like I would expect from ventoy, but it doesn't render the UI correctly at all.


It does this both in Virtualbox and real hardware.

Is there any way to get this working for a pre-existing EFI folder?
