CentOS

New to CentOS. Can't workout why i can't get full screen
Seems to have to do with ...Kernel headers not found for target headers
Please install them and execute /sbin/rcvboxadd setup
modprobe vboxguest failed

I apologise if this makes no sense or is completely basic, but i hope some will understand my inexperience and help with instructions for a complete beginner.

In addition if i click on Devices > Insert guest additions cd image. I get the following Unable to insert the virtual optical disk c:\program files\oracle\virtualbox\vboxguestadditions.iso into the machine centos

First, you need to install kernel headers: Then, you need to make VirtualBox attach the guest additions DVD and install from there.

Thank you

I successfully installed kernel headers with the yum install kernel-headers as suggested, but still getting the same error. I have attached some shots with the hope they will help.
Can't copy from guest to host until I've installed guest additions hence the screenshots.

I don't see any screenshots .
Can you provide the errors it reports ?

Hi Hunter, i'm sorted at the moment. Thanks for your help. Not sure what happened to the attachment, but just in case you still want to have a look I've attached again.

What is the content of the setup log (in your last screenshot)?
You can use pastebin.com to paste it there.

The version of kernel-devel needs to match the version of the running kernel exactly. If you run uname -r then that is the version of the kernel-devel package that needs to be installed so to check if it is, run rpm -q kernel-devel-$(uname -r). Now reboot into the latest kernel and try that again and see if it gives output now?
