Download GParted from somewhere you trust and burn it to a disk. GParted 
can move and create partitions--you start your machine on GParted from 
the disk and go on from there. You need to keep the Windows overhead--
the first three partitions, but the third one (if I remember) is the
user partition, and can be shrunk to 100GB or so. Windows also has a
partition way at the end of the disk--leave that. Now you have a large
space between the Windows user partition and the small Windows partition 
at the end of the drive, on which to put your Ubuntu system. I'm not
an Ubuntu user, so I don't know how best to partition it, but on
another distro, I like a / (boot) partition with the system overhead on
it, and a /home partition with your user stuff on it.You may want a swap 
partition. There are other schemes, with many partitions, and Ubuntu may 
default to one large partition with everything on it. (I think this is 
dangerous--if you need to reinstall, your personal data is lost.) I am 
not a maven, so there may be some better advice out there, but this is
at least a beginning.   --doug
