Multiple OS in your PC

Here is my partitions mapping for working pc.

Notes:
- I used Partition Magic 8 for Windows,
  it correctly resizes ext3 partitions
- Partition Magic 8 seems not to be able to recognize unsed space over Fedora
  Core 3 partitions, for this reason I created the partition with the correct
  size before installing it.
- Use the label "Fedora" for the partion hosting Fedora Core 3, 
  particularly do not use blank spaces
Configuration 1

Windows XP - Red Hat AS 3.0 - Fedora Core 3

  1. Install Windows XP
  2. Install Red Hat 3.0, use Grub on Master Boot Record
  3. Install Fedora Core 3
  4. Now you will be unable to boot Red Hat AS 3.0 because of invalid Grub configuration
  5. Mount the Red Hat AS 3.0 partition from Fedora How to mount on Linux
  6. Go to /RedHatAS3.0/boot/grub/grub.conf and copy the boot string to the /boot/grub/grub.conf in Fedora, if you need help on Grub please see GRUB
