In this setup I'm using Oracle VM VirtualBox which can be downloaded here, feel free to use your own VM...
First of all open Oracle VM VirtualBox and click on the New button:
Then in the new window choose a Name for the operating system, I will go with 'Rosehip' but you can choose anything,
and for the Machine Folder I will choose 'C:\new' but you can choose anything (if you choose a folder which doesn't exists the VM will create it for you),
then tap on the Type section to open a drop-down menu and choose Linux and in the Version section choose Other Linux (64-bit)
and click Next.
Choose how much RAM you want to allow Rosehip to use 2GB-4GB would be reasonable (it won't actually use all this RAM but if you give it high limit it will perform well) and press Next
Choose create. Choose Next. Choose Next.
Now you should see a window asking how much storage would you like to give to Rosehip, choose how much you want, (you need at least 300MB) and press Create
In the new window click on Settings:
In the settings window choose Storage:
In the storage section delete Empty by right-clicking it then pressing Remove Attachment then pressing Remove.
Press Controller: IDE and then on the little disk icon:
click on Add and find the iso file you got from CITUR then press Open then press Choose.
Go to Display section:
And in the Graphics Controller pick VBoxVGA:
Press Ok and press on the green right arrow Start
In the intrepreter just type the word "rosehip" to open the desktop
