I would recommend that you defragment and then go for a disk cleanup. You would be able to access those through my computer and then a right click on local disk. Once there, try the tools tab for a defrag and then general tab and disk cleanup. I might have the defrag and cleanup in the wrong order, but those two will definitely help. though they both can REALLY KILL SOME TIME. You might have to set it up and go out for dinner or something!
Delete stuff that you dont need or dont use.
------------------------------
You can follow the steps to enable Disk Cleanup utility:
Delete data you don't need, delete temp files, uninstall programs you don't need, and then defrag the hard disk. Windows also has a Disk Cleanup tool, which can also free some space. It's in the System Tools folder in the Accessories folder.
Assuming a Windows PC is the host:-
1. Remove files no longer relevant, i.e. not needed by applications and utilising space you want to get back. Work your way through the directories and delete anything you know to be no longer required. It will go into your 'recycle bin' and will only be truly deleted when that's been emptied... so if you make a mistake your can restore it from there. You could burn the files off to a CD/DVD if you wanted backup copies of them.
A good place to start on a windows PC is the 'temp' folder which resides in the 'local' directory under your user name on the C drive. So that's C:/Users/{username}/AppData/Local/Temp.
There are applications that do this such as SpeedyPC Pro - but you can do this yourself.
2. Defrag your hard drive. Files on a nearly full drive tend to get fragmented over time and running defrag can recover some space by concatenating these. This is often marginal but can also improve load times for files.
By deleting unneeded files. You can also try clearing the apt cache (the downloaded packages) by using the command sudo apt-get clean

You will have less disk space available for OSes.
If by "Cleaning up" you mean "deleting data" then space Will free up.Defragging or "Checking Disk" will not create free space.
Ubuntu uses the ext4 file journaling system, which doesn't get fragmented.
dynamic space
Yes, it can be done from the windows installation disk, but it's cleaner if you remove ubuntu with the ubuntu live cd and then install windows.
Recent versions of Ubuntu Linux require about 5GB of space.
Well, if you have a DVD burner drive, which is pretty much standard on computers today, you can just download the Ubuntu ISO image and burn it to disk without a fuss. There used to be a program called ShipIt that would send you a copy of Ubuntu free of charge, but Canonical shut it down. Otherwise you'll have to spend a (Nominal) amount of money to buy a copy from sites like Distro Watch.
Ubuntu is a free system program. Therefore, all of the software which comes from Ubuntu is free as well. One might want to check out from the main website of Ubuntu.
No. After download and burn the Ubuntu 10.10 install disk, you can either TRY Ubuntu without affecting your Windows at all, or INSTALL Ubuntu to have them both in your PC. However, to install Ubuntu, you need to be careful. Make sure not to install Ubuntu to the Windows drive. That is all.
Mine in particular: about 120gb.
