How to install fedora15 and hard disk partition on a USB flash disk

How to install fedora15 and hard disk partition on a USB flash drive-Linux general technology-Linux technology and application information. The following is a detailed description. I felt a little timid and did not dare to try the system, because I used to delete the Startup Program, and the computer would not start.
I searched for a lot of different sayings on the Internet, so it was strange. I would like to ask some familiar experts for help and explain the hard disk partition and fedora15 installation problems. I have read more about the installation steps on Wikipedia, but I have not specifically stated what formats are required for hard disk partitioning and how to set dual system boot.
In the hard disk partition, the partition is extended from Windows. Is it delete something? Is it the right-click Delete? After the change, the labels are unallocated or fat32.
Well, there is a live USB creator installed on the USB flash drive, but I didn't see it in the forum. I want to know if it works better. Those code strings do not know the specific meaning of each step, and sometimes they are afraid of installation errors.
I am currently using xp, want to install it on the D Drive, use partition magic partition, and install the USB flash drive. Can you give me a simple step? Thank you.
