Why Won’t My RECON ITR Boot?
Last Updated 2 years ago

Some of our customers reach out, saying that they are experiencing trouble getting their bootable USB to boot. Below are some of the common fixes that may resolve your situation.

1. Which drive are you using? - RECON ITR comes with two separate drives one for the bootable version of RECON ITR and one for the live version. If you are trying to boot to RECON ITR be sure that you are using your 32 GB Samsung Duo USB drive and not the T7 Drive.

When using the Duo drive also ensure that the entirety of the drive is plugged in not just the adaptor. The Samsung Duo is a USB Type-C drive that comes with a Type-A adapter, when using the adapter make sure the drive is also plugged in.

2. Have you disabled the Startup Security? - Macs with T2 Security Chips require you to disable startup security if you want to boot to external media. Check if the Mac you are trying to boot has a T2 by looking at the. model number and checking the release date against the list below.
