Kernel doesn't support 64-bit CPUs

I tried to install from kali-linux-2023-1-live-i386.iso on a usb key. The installation went without any warning. On /dev/sda there are 4 partitions ; /dev/sda1=/boot/efi /dev/sda2=fedora38 /dev/sda3=fodora(old) /dev/sda4=kali . Kali doesn't want to start from grub after this installation. I tried from the command line , typing "c" on the grub menu and I got thevmessage in the titre :
Linux.c:416: kernel doesn't support 64-bit CPUs. I can access the kali partition from fedora chroot. What's wrong ? The computer is an ASUS VivoBook.
