Black Screen when install Security Onion on iDRAC

Hello.. I'm experiencing an issue while installing the Security Onion OS using iDRAC on my R450 server. The problem I'm facing is that during the installation process, I insert the .ISO file into the virtual media and boot from "virtual CD/DVD/ISO". After the reboot, the installation process runs smoothly, but after a few minutes, the loading process turns into a black screen. I have also made sure that my Security Onion ISO is intact. I would appreciate any assistance from anyone.
