I don't know a best and easiest way, but I am going make a suggestion:
Open Control Panel > System > Advanced (tab) > under Startup and Recovery
click > Settings > under System startup click > Edit
Click File > Save as, save it to a remote location such as a Floppy for
example, even better, burn it to a disk, you are gonna or might need it
later.
Boot into Windows XP, insert your XP CD-ROM, launch setup install XP on the
partition on which Vista was installed. If you are unable to install XP
because you have a later version of XP installed compared to whats on the
disk, then you need to boot off the disk into setup.
XP will start into the text based portion of setup, select the partition on
which Vista was installed and install XP. The possibility that it might find
an existing installation of XP is likely, but it is also likely that both
are incompatible because they are two different versions (ie. XP RTM vs. XP
SP2), meaning, the one you are installing fresh from the disk, might have no
Service Pack and the one on hard disk does.
Do not attempt to fix this installation, go ahead do a fresh installation on
the partition Vista was installed.
Its possible that this procedure might add the existing install of XP to the
fresh installs boot manager or it might not. If its does not, this is what
you are gonna do. Remember that file I told you save earlier? This is where
it comes in. Copy it to the desktop from the remote location floppy, rename
it BACKUP.
Open Control Panel > System > Advanced (tab) > under Startup and Recovery
click > Settings > under System startup click > Edit
Add this entry to it:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /FASTDETECT /NOEXECUTE=OPTIN
If the old XP install is not on C, change partition(1) to partition(2)
It should look something like this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP
Professional" /FASTDETECT /NOEXECUTE=OPTIN
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP Professional x64
Edition" /NOEXECUTE=OPTIN /FASTDETECT /USENEWLOADER
