There is an additional option during installation summary where am asked for installation source. How do I set up the installation source?

Hi!
after waiting this 60 seconds nothing happens only a blinking sign!!

Doesn't work as of VirtualBox 5.2.6 and Fedora 27 kernel 4.15.

after inserting the guest additions CD image, I get a repeated message in the terminal window that "this system is currently not set up to build kernel modules". It also tells me that "the distribution packages containing the headers are probably: kernel-devel kernel-devel-4.14.7-300. fc27. x86_64. I am very new to Linux and VM's as a whole and need to become familiar with it for an internship. Any help from this point on would be greatly appreciated.

what to do if after loading in the iso it shows a caution sign

I installed it, but after the reboot I still have only live version of Fedora...Any idea what's can be a problem?

inserting the additions cd only opens the file explorer for me, it doesn't give me a popup to run any software...

Trying on some Fedora to see how it fits.
