I'm running Virtual box on windows. I installed ubuntu as a guest. Everything is working fine, except i'm trying to install the Vbox guest additions, which helps the graphics, etc. This is basically like VM tools under VM ware. ANyway, when you 'install' the vbox guest additions it mounts a cd on the desktop. So the guest thinks there is a cd rom in the drive. I click on that 'cd', and it opens up a window. The file i want to open is called "VBoxLinuxAdditions-x86.run", Now when i double click on it a white terminal box appears, and it says something to the effect of this progam needs to be ran with administrative privileges. I tried all kinds of different "sudo" commands in front. any ideas? the google and the web aren't much help, since the commands don't work.. indygun?
