Raspberry Pi 4 USB Boot Issue

Job ID: 38643669

Budget: $30 – $250 USD

My Raspberry Pi 4 isn't booting from a USB flash drive containing a FreePBX image file. I'm not sure if I've successfully booted from a USB drive with other operating systems before.

I need a professional with:
- In-depth knowledge of Raspberry Pi, particularly the Pi 4
- Experience with FreePBX
- Proficiency in diagnosing boot issues
- Expertise in USB boot processes

Your task will be to troubleshoot the issue and get the Pi booting from the USB.
