The 20Gb on d: is more than enough for my files. Given that I don't *need* more space from the c:, should I just let Edubuntu have the whole 10Gb as a single ext3? I'm not sure what real advantages I'd get from partitioning c:. If I keep all my files on d: (I can reassign Linux to save all documents to d: right?) then in case I wanted to install an OS from scratch then I don't need to worry about backing up files on c: - correct?
Do I need to worry about AV/Firewall/Defrag as a Linux user? :D
