I'm having the same problem too. I installed a new Windows XP Professional without deleting the old one(XP Home). So now I have two different Windows XP and it takes up a lot of space. Do I have to insert the Windows XP Disk to uninstall the old one? Because I don't have it.

If you have two different installs...on two separate partitions...there are only two considerations that I know of:

a. Each install is independent, as long as they are on different partitions. Simply deleting the one that you don't want (e.g., via Disk Management) will take care of that...but if they are on the same hard drive, that may create a problem.

For example, if installing Windows XP/2000 when a Windows XP/2000 system is already installed on another partition, the installer may configure the boot loader (NTLDR) on the older installation, to boot both the newer installation and the old installation, and not install another NTLDR on the partition of the new installation. This can create problems as the new partition will be dependent on the old partition, and will not be able to boot unless both partitions are properly configured.

B. XP Home and XP Pro both use the same boot.ini file. So the boot.ini file will have to be altered, corrected. This is easily done, in most cases.

The above is further possibly complicated by the existence of recovery/restore partitions.

A screenshot from Disk Management would simplify any suggestions that viewers may want to give.
