I think XPUser4Real has got it right.

You probably have to install XP Home on the Dell 3000, from scratch.
A Repair installation of Windows procedure definitely won't change the existing Home or Pro designation.

If you haven't installed much on it yet, that's no big deal.

If you HAVE installed a lot on it already...

You could
- use a third party (partition manipulation) program to shrink the size of the C partition to make lots of unallocated space available - e.g. to the minimum size it allows, with a reasonable amount of free space added.

NOTE that the Home installation (the second installation of Windows 2000 or XP) will use D or higher for the letter of it's installation Windows is on, unless you HIDE the all hard drive partitions that are visible and have a drive letter in XP Pro BEFORE you run XP Home's Setup, by doing that with a partitition manipulation program. In that case, you must use a bootable version of the partitition manipulation program, to HIDE that (those) partitions. E.g. Easeus Partition Master can make a bootable CD after you install it on the Pro installation. )

- install XP Home in the un-allocated space - make a new partition with the CD before you actually run Setup.
- you will then have a dual boot configuration
(if you HID the partitions on the hard drive before you ran Setup,. you will probably need to set that up manually after un-HIDING the Pro installation - or you can do that with a program in the Recovery Console when you boot using the Home CD.)
- transfer or copy all the stuff you can in the Pro installation to the Home installation
- delete the Pro partition
- use a third party program to increase the size of the C partition to use the unallocated space available.

third party (partition manipulation) program ?
Easeus Partition Master Home Edition (freeware)
(Very good.)

If your XP CD does not have SP3 updates included.....

See Response 6
starting at
"If your XP CD does not have SP3 updates included, the best time to load them is right after you have installed Windows from scratch...."

If your XP CD does not have any SP updates, if Setup has already been run, you will have to load SP1 or SP2 updates before you load SP3 updates.

Regular Microsoft XP CDs have SP2 or SP3 printed on them if they have those updates included. All the regular Microsoft XP CDs that have SP1 updates included that I've seen DO NOT have SP1 printed on the CD, but the volume labels - the labels you see for the CD in Windows - for CDs with SP1 updates included are different from those with no SP updates at all - you can search using that volume label to determine whether it has SP1 updates or not.

Brand name (OEM) XP re-installation CDs usually have SP1 or SP2 or SP3 on them.
