@Blmoe Sorry i guess i misread that:
Please check if your UEFI is 32bit:
Boot a Manjaro Boot Disk, then open a terminal:
sudo modprobe efivarfs
then
mount -t efivarfs efivarfs /sys/firmware/efi/efivars
and then
cat /sys/firmware/efi/fw_platform_size
It should display 64 for 64bit, if it is 32, then unfortunately it is not officially supported. But there is way to install it with 32bit UEFI.
Maybe this guide you to a solution: Can't install Manjaro KDE 20.1.1 on an UEFI 32bit hardware - #7 by AlanP
