I am relatively new to Linux and Ubuntu. I had installed Ubuntu 7 but could not get the internet connection to work. Now, while trying to install Ubuntu 8.04 after cleaning out 7 by deleting and restoring and formatting partitions the installation of Ubuntu 8 hangs at 82% while Configuring apt and scanning CD-ROM. I gave the system 18 mins to do this during which there was no DVD drive activity and no change on screen. After power down I was able to reboot Windows XP on its partition. The same happens if I try to install from the live session. If I go to the drive via Places and double click the drive I get 'Unable to mount location. No media in the drive.'
Any suggestions for how I might install Ubuntu 8.04?
