Hello @tomago83,

Can you let us know what OS are you trying to install? Have you tried the ISO on another system to check if it is able to be used for installation?

Have you updated the iDRAC/LCC and BIOS, just to make sure everything is up to date for the OS.

May I know what model of server you have there?

Can you take note if the ISO is mapped as shown in time 2:46 of this video: https://dell.to/3myGOtI

Can you try another ISO to check the root cause.

It would be great if you can provide us some screenshots of your installation process and the issue.

Windows Server 2019

iso works fine - the server can boot from it, but i want to install from lifecycle manager

brand new server R440, i have 2 of them and tried both

Hi,

Thanks for the screenshot and confirming that the ISO works fine when using it as boot device.

That is weird that 2 server are having the same issue. 

Here's what I can think of, if these doesn't work, I suggest to call into support to log a case and have them check if a replacement is needed on the last resort.

Try a soft reset of iDRAC: https://dell.to/3iDHrRw

Try on another client system accessing to iDRAC and mount the ISO file.

Try changing iDRAC plug in type from HTML5 to Java. 

i have reset iDRAC - no difference

i have tried multiple clients, and browsers connecting to the iDRAC - same issue

can't use Java, don't have it installed on any device

will have to raise a call

Are you mapping virtual media after entering to lifecycle controller? If yes can you map virtual media then boot to lifecycle controller and try.

I had the same issue and your proposal to first map the virtual media and than entering the lifecycle controller solved the issue for me.

I came across this yesterday trying to boot an r740xd2 with an Ubuntu server ISO.  Thanks to those who mentioned to map the virtual media BEFORE entering the lifecycle controller.  That did the trick for me.
