Hi Christophe,

Since you have a UEFI shell available, your BIOS is already UEFI only.
This board does not expose CSM/Legacy toggle because it does not
support it, so that's not that issue.

Two things to try:
1) Go to `Boot Maintenance Manager` -> Boot Options -> Add Boot Option,
select the USB device 
navigate to `EFI/BOOT` then select .efi file. Save it then try booting
entry directly instead of using `select boot device` menu 

2) Try booting manually from UEFI shell,
In the shell run `map -r` 
It will print out recognized file systems (fs0,fs1,etc) then find the
one that corrosponds to your USB key then 
`fs0:` (replace this with your USB key)
`cd /EFI/BOOT/`
BOOTLOONGARCH64.EFI.


If map -r doesn't show a filesystem for the USB key, that confirms
the firmware isn't reading the partition ESP correctly, and
Ventoy (formatted FAT, per Ralf's note) or a BIOS update would be the
next steps.

Best,
Shivank
