In this step, you have to choose the size of the persistent data that could be stored.
This feature is currently not working when using VirtualBox in Seven/Vista.
Before going further, I recommend you to give a look to these questions in the FAQ :
- What is persistence ?
- What can i do and not do on a Persistent system ?
- Why can't I have more than 4GB for persistent datas with LiLi ?
- How can I have more than 4GB of persistent datas ?
If you don't know how much to give to persistent data, give between 300MB and 500MB. If you intend to make an heavy usage of your Linux, choose more than 1 GB.
Putting 0MB means no persistency, only live mode. All changes made in your Linux will be lost on reboot.
Be warned that you must not do system updates. Explanations here.
If you don't have enough space, select the "Format" options in step 4.
