Failed install: Boost.Python error in job “bootloader”

@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
