Zorin OS

I was a mathematician professor in a pré-university school in Ghent, a beautifull city in Flanders, Belgium. My studies did I on de University of Ghent. For many years at the and of my carreer the computer overwelhmed me and I became an addept. I longtime programmed in different 'old' langauages asl Cobol, Basic, Pascal (for the beauty) and so on. Then I followed the different Windows OSses from Win 3.1 to today Windows 7. Alternately I began to intrest me in Linux. I did some approaches to learn to use different distributions as: Fedora, Mint, Ubuntu, and so on.   For the time I would take an experiment to instal Zorin OS after my  Win 7 on my pc. I hope Grub2 don't trouble my good working system. First of all i must download a iso-disk of Zorin OS.
