1:if you have a second PC, use it as your Linux learning machine.
2:If you are not familiar with partitions from Windows, then you probably don't know as much as you think.
Very quickly using regular consumer hardware,
/dev/sda -- this is the first disk device as presented by the BIOS. If the disk has no partitions, then that is all Linux 'sees.' Installing most distros will be really easy.
/dev/sda1 -- this is the first primary partition of the disk. The next primary partition will be /dev/sda2
/dev/sda4 -- a logical partition. If you have split an installation of windows to simulate the handy Unix "/home/" concept, Microsoft loves to use logical partitions beyond root.
If you have only one system, the easiest way to install Linux is to reinstall windows and partition the disk yourself leaving about half the disk empty. Also be aware that some distros expose more install options to a user than others. I like Debian myself. As long as you have empty space on the disk it should be easy in Debian. Debian experiences are very, very well documented.
You asked for help and you got some. Great, right? Now go and learn and then offer your knowledge to others.
