Typically this has one of the following causes:

1. Corrupted ISO download.
   • Verify that the ISO checksum post-download matches the published checksum.
2. Bad Copy/Burn to USB/DVD
   • Many popular image burning tools do not handle FreeBSD image files properly. The best way is to use the "dd" utility on a Linux/BSD system with the following command: dd if=[path to ISO file] of=/dev/[USB device - make sure this is not a partition on the stick but the whole device!!] bs=5M conv=sync
3. BIOS Configuration
   • UEFI mode is recommended, but CSM mode for UEFI must be disabled for optimum results.
