[SOLVED] How to detect booted mode (UEFI vs BIOS)

[swiley43]

Hello

There is a way (a variable) to know if Ventoy pendrive booted in UEFI mode or in BIOS (legacy) mode, and to select the displayed theme : one for UEFI mode and another for BIOS mode.

Thanks

grub_platform is a builtin variable in grub2, for legacy BIOS mode it is like: pc, for UEFI mode it is like: x86_64-efi

Currently, in the bottom left of the boot menu will display:

1.0.24 BIOS www.ventoy.net  ----> This means current is Legacy BIOS mode
1.0.24 UEFI www.ventoy.net  ----> This means current is UEFI mode

Thanks

How can I use this variable for changing the Ventoy theme : one BIOS theme vs UEFI theme ?

I just support and commit it, the feature will be avaliable in the next release.

You can use Ventoy-1.0.25
