I'm currently upgrading my 3595 ISE server from USB using http://www.cisco.com/c/en/us/td/docs/security/ise/2-2/install_guide/b_ise_InstallationGuide22.html ; guide. I downloaded the recommended Live USB creator, but unfortunately, I keep receiving the error, syslinux/vmlinuz is image not found. I also tried to upgrade from the GUI using the repository using 3cdaemon, but during the actual upgrade process, the preparation upgrade never completes. Can anyone please assist me with a possible solution?
