If you can run your windows ok, you can run your linux on an external HDD. This proceedure is far simpler and required a lot less faffing about with CDs and other things.
First you need to buy a external HDD, (or you can use your internal HDD.)
If you buy a hard drive over 100 GB you may want to partition it. partition tools are available on the ultimate software list. Partion the harddrive so that you have 80GB at the most on the place where you are going to place Ubuntu.
If you ar going to use you internal hard drive you may also want to partition it as you will only need around 50 GB.
Once you have brought your hard drive, you are gong to need to Google, 'Wubi'.
This program, is extremely simple to use and is reliable.
It will ask you where you want to place Ubuntu and you place it in the 80 GB partition
Then once this has been done you are going to need to place the BIOS boot of the external HDD not first, but maybe 2nd or third.
If you have any other trouble just say so, and ill try my best to help!!
Good luck
