Hi all, I'm don't have any experience with any unix-based systems before, so sorry for possible stupid question... I have some problems with free disk space in my laptop, therefore I pick out only 6GB for new fedora installation. In configuration I chosen all parameters as default. After successfully instalation I have only 700Mb available disk space. Is it ok? If so than what I can remove for free some more space? Or is it possible to attach someway virgin disk space (detached from ntfs) to fedora file system? Thank you in advance.
