I think the option you want to mount a virtual CD ISO is [Virtual Media] - [CD-Rom Image]. When asked for the path to the ISO, you should be able to browse to the folder on your PC and select the ISO.
*** Depending on the software, there may be a checkbox to make it use the ISO, but I can only reference my IPMI software from Dell so it may differ for you.
*** Also, in my IPMI software I have to leave the "Virtual Media" dialog opened otherwise it will discontinue to map/mount it.
When booting up the Server, you then should be able to select a boot option and tell it to use the "Virtual CD".
*** Should not need to setup any Share on your PC to do this.

Here is a screenshot of the screen that I see. I do not have an option to browse my desktop HDD for a file.
Each time I put in what I Have stated in my last post, I receive an error. It is not immediately known to me the issue. I do know that ultimately, it will create a UNC path.
