I am trying to do a dual boot on a Dell Inspiron 1721. I have found several guides and they all seem to be pretty similar in shrinking the volume and seting up new simple volume for XP. I have allocated 40 GB for the new XP drive but have a problem when i try and set up a new simple volume. I follow the steps but when i click 'finish' I get an error message that says 'There is not enough space available on the disk(s) to complete this operation.' I was wondering what i have to do to get around this.
