Hello,

 

Trying to reimage new 3615 boxes with 2.4 image with new ISO. I followed Cisco doc as it.

 

https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/install_guide/b_ise_InstallationGuide24/b_ise_InstallationGuide24_chapter_011.html#id_12079

 

performed step 1 to 10 from above document. After reloading boxes and booting it from USB , I did get notification for below

 

Cisco ISE Installation (Serial Console)

Cisco ISE Installation (Keyboard/Monitor)

System Utilities (Serial Console)

System Utilities (Keyboard/Monitor)

 

 

I chose Cisco ISE Installation (Keyboard/Monitor) but after this I got an error (please see the attached screenshot).

 

error: /syslinux/vmlinuz has invalid signature. Please help me to resolve this issue.

 

Thanks

 

Aravind
