If you’re a Windows user and haven’t tried a proper install of Ubuntu (not Live CD), shame on you! Especially now there’s no excuse not to thanks to Wubi. Wubi is a Windows based installer for Ubuntu which magically installs the OS as a folder on your regular Windows partition. Removing it is as simple as deleting a folder in Windows. Nice.
During installation Wubi will search for an ISO of the alternate Ubuntu 7.04 install disc, if you have it saved locally alongside the installer it will use the ISO, or else go to a default (read slow) mirror to download. I recommend you torrent the alternate install ISO first for obvious reasons.
Compatible with Windows XP currently. No Vista support!
