You need to switch the DVD mid installation for the drivers. Then you can load the drives and reinsert the Windows Install DVD.
A portion of that can be found in my guide: https://steemit.com/linux/@uni…make-yourself-a-gaming-vm the section about VirtIO drivers.
Please keep in mind that you need advanced knowledge on securing Windows - otherwise it is a matter of hours until your server will be hacked and therefore closed by Netcup to protect it's customers. You are directly responsible for any attacks that will be launched from your server - especially financially responsible.
Since you have problems following simple guides, you shouldn't run a Windows server on the public internet without any firewall in between.
thank you for your information, much appreciate your time writing a guide out for the community. yea its quite advance as its beyond my knowledge, as of before, i just purchased a vps window server and it was abit expensive, so therefore, i wanted to try out to do this root server myself. however it was too advance and i needed some help. the guide from the above member which i followed had some issue with the kvm installation. i try to overcome this now, running your guide might help to iron out some of the issue i am facing. but thank you for your care about the security measure as i understand it is very important to have this concern in mind.
