I don't have words to thank both of you enough for guiding me with sincerity in the selection of Unix\Linux system.
I have started learning Python and Ruby as well.
After a few search I have a found this link tech-faq.com/where-to-download-unix where you can download different types of Unix\Linux. As you mentioned that OpenBSD or FreeBSD has more advantages, however you can always explore to other one.
it seems to me that you can download and burn the installation files to CD. Just wondering whether you can install BSD in external hard drive, so I don't need to install another internal hard drive for specific to Unix system running.
Is there installation instruction after downloading it to the hard drive?
Thanks a lot
New User of Unix
