2. MetaDefender OT Security Enterprise Manager flashing and installation
In the last section, the only thing left is to install MetaDefender OT Security onto the machine, which is accomplished almost automatically by the system.
- Plug in the MetaDefender OT Security USB that the user created in the first step.
- Press the power button to turn on the device.
- Repeatedly press F12 (usually) or F11 (on a 1U dedicated server) at the splash screen to select the Boot Menu option.
- Select a connected bootable USB.
- Boot from the USB in the UEFI mode. Pay attention to the USB brand name to avoid choosing the wrong one.
- Booting is a process that has appeared with boot menu options:
- MetaDefender OT Security - Use this first (leave it default). It enables normal graphics support and is suitable for most PCs and workstations.
- MetaDefender OT Security (Safe Graphics) - If option 1 shows errors, a black screen, or stops during early boot, restart and choose 2. It avoids aggressive graphics setup so the installer can start on servers, KVM/BMC consoles, or systems with non‑standard displays.
- MetaDefender OT Security (Fallback Graphics - blacklist drivers) - If 2 still does not boot, restart and choose 3. It turns off common GPU drivers so startup can continue on hardware where those drivers cause problems.
- Wait for the first stage installation until the pop-up asking to select a component.
- Select the component, click Next
- Select the Hard disk
- The application is flashing
- After flashing is completed, click OK to shut down
- Unplug USB (Important!!!)
- Turn on the machine again to start installing
