It should be possible to install Ubuntu from inside Windows with wubi depending on your machine.
If you cannot use wubi to install then make a backup of your machine, read some documentation about partitioning disks and Linux filesystems then try out the installer.
The layout of Linux and other unix systems are not like Windows with regard to drive letters, everything starts from / the root of the filesystem and then branching out to say /home/someuser for user files and /dev/* for device files etc. Maybe look up Filesystem Hierarchy Standard or the hier man page.
Hope you manage to get up and running with Ubuntu (or any other flavour, for me it's Gentoo :).
