Basically i'm helping out at the offices where family works. They have this backup server computer - which is running Ubuntu 10.04.2 LTS - which they apparently in the past could just turn on and then they could make backups from their windows computers.
This is not my forte at all and I assume it appeared simply like a network drive/share that they could access. But, when I connect it now it only boots up in command line/cli mode with no gui with a login screen. and it doesn't appear on other computers when network discovery/file sharing is turned on etc. I really want to be able to access the standard ubuntu gui like I can when using the Ubuntu livecd (I have burned the Ubuntu 14.04.2 LTS iso to disc). When I click the install option from the livecd it asks whether i'd like to upgrade the current ubuntu to the livecd version (14.04.2) - im not sure if this would add the gui or not. and it says "will clear system-wide settings" so I'm worried this will stop the backup/server settings from working, not sure. OR ideally I could just add the gui to the current computer without having to upgrade/install, as im paranoid of ruining the backups on the hard drives. (no external drive to back everything up to) please help?
I have tried logging in and doing commands like startx etc but it doesn't work.
tl;dr: I just basically want to access the normal Ubuntu gui mode and get this server running again. technically minded but do Not have any real experience with linux at all except with simple tasks
