Install multiple linux OS on a single PC

Now a days there are so many Linux distributions and also each of them has their own speciality. There are many users those who have dual boot OS(two different OS on a single machine). Many of my own friends have fedora/Ubuntu and Windows OS installed.

Today I am going to say about how to install fedora, Ubuntu, and Windows XP on a same PC.
1: Install XP
2: Install Ubuntu
3: Install fedora.

Note: When you install fedora after the installation of Ubuntu your Ubuntu's grub will be removed and you can't see Ubuntu on the Grub's list.

Now, to get the Ubuntu on the Grub's List follow these Steps:
1. boot with fedora
2. open terminal
$su -

as root type this command.
# fdisk -l

Hint: Check Column "System"
Lets /dev/sda3 partition contains your Ubuntu OS.
3. mount your Ubuntu partition.
# mount /dev/sda3 /mnt
4. Open the grub menu.lst file
# cd /mnt/boot/grub
# gedit menu.lst
Now search for similar lines:

---

Copy these lines and paste these inside the fedora's grub menu list file:
# gedit /boot/grub/menu.lst
now restart fedora OS
This time you can see few more options on your Grub's List.
