SCCM: creating bootable USB disk for OS Deployment and ends with “Failed to create media (0x80070057)”

I couldn’t create a bootable USB disk to deploy an OS for some reason. As usual Microsoft error is useless, it doesn’t actually tells nothing about the actual issue.

All I get was “Failed to create media” and reading logs doesn’t lead to anywhere.

Strangely these two things worked the magic.

1. Disabled Antivirus (frigging Symantec Endpoint Protection, I hate this stuff)

2. Disconnected all network drive mappings (run Net Use * /delete /y  in command prompt)
