It is not possible to install any Operating System next to another on the same partition. To dual-boot Windows 7 and Windows XP, first install Windows 7, and while in the partition manager, delete all partitions and create one for Windows 7 and one for Windows XP. Then install Windows 7 to it's partition. Then install XP to it's partition. You should now be able to boot either Operating System.
Note: You must install XP after Windows 7 as the Windows 7 installation wizard would want to upgrade XP.
WARNING: This will erase all of the data on your hard drive. Be sure to back up all of your files before installing anything.

It is very easy to do this. The only thing you must remember is that you cannot install windows 98 from Windows XP environment. Either install 98 first and then XP or after installing XP reboot in DOS mode. The install will ask for the drive to install to when you do so?
You have to create at least one more partition for Vista. If you install Vista on the partition where XP is installed Vista will delete XP. To avoid such problem you have to have one more partition. When you do that just start the Vista installation process from XP and choose just created partition for Vista.
It's highly recommended to install XP on NTFS partitions.
Of course you need to partition your drive. If you already have installed Windows XP You need to make a new partition for win98 formated FAT32. WinXP use NTFS formatting.
You cannot reverse such process especially after you have installed the os. But if you remember the old partition size you can format the disk again, delete partitions which you don't need and create a partition which you want to have.
Start the computer and insert the XP installing CD, and when the process gets the partitions management section, delete the partition in which the W7 is installed, create a new one for the XP, and begin formating the XP.
Primary NTFS Partition.....
Yes Linux can be installed on the same computer.
Use your Ubuntu CD. Find a program called "GParted" or "Gnome Partition Editor". Click on your XP partition and click "Resize" and make it smaller. Then, do the same with your Ubuntu partition, and drag it until it fills the space left by XP.
Absolutely. During XP setup, you have an option to choose where to install the OS. Just choose to delete your existing partition, follow the instructions, and then create a partition in the empty space and install XP there. Please note that this will delete all of your files and settings unless you have them saved at a different place such as an external hard drive or another partition.
