This is a gxmessage based Installation assistant for nanodesk.

To install nanodesk you need a partitioned and formated drive.
You can do the partioning and formating with 'GParted'.

If you need help how to do so, click on 'Help'.

When you are done partitioning and your installation target is formated,
go ahead with 'Install'." |
