Cannot boot USB - Grub rescue

I’m using a macbookpro with Ubuntu - just installed - no problems. I’ve also used Manjaro before without any problems. What can I do?

Thank you!

sudo dd bs=4M if='/home/robin/Downloads/manjaro-gnome-20.2.1-minimal-210103-linux59.iso' of=/dev/sdb conv=fdatasync status=progress && sync

error: unknown filesystem

Have you disabled Secure boot in firmware?

Yes, when I boot Ubuntu it says “Continuing boot because secure boot is disabled”

I kinda solved this by deleting the whole SSD leaving nothing left except the Apple recovery mode, downloading MacOS from scratch. After this I could boot the Manjaro OS USB.

is there any other solution to this problem ?
i want to try manjaro as i am done with windows .
