So you’ve gotten started with Linux, but you’re looking for a new flavour besides Ubuntu to try out. Instead of installing a bunch of them from scratch, web site Virtualboxes provides a bunch of free Virtualbox images for you to test out, no installation required.
Virtualbox is a great way to try out software and operating systems without having to partition or reboot your machine, but you still have to download live CDs and go through installation procedures. Web site Virtualboxes hosts a number of Virtualbox images for a bunch of different Linux distributions and other operating systems. That way, if you’re ready to move on but you aren’t sure what you want to try next, you can give them a shot in Virtualbox without going through all the tedium of installation (or the annoyances that come with Live CDs).
