Error: unknown filesystem, entering rescue mode on boot from USB

I’m trying to boot from a USB and it comes up with error: unknown filesystem
grub rescue. I’m trying to boot to Manjaro for a peek. If I boot using a Fedora boot, no problem.

Any ideas? I’ve never encountered this before

I figured it out. I simply used Fedora Media Writer, changed the system to Arch, and voila, I had a bootablr disc that worked.
