Also, will an XP Home edition product key work for XP Professional edition? Guessing no on the second question.

Short answer: maybe — but not reliably. A Dell "reinstallation" or recovery disc is usually OEM media tailored to Dell hardware: it can contain Dell drivers, branding and an OEM activation path that looks for Dell BIOS/Service‑Tag information. On a custom-built PC the installer may run, but activation can fail or it may prompt you for a key because the OEM pre‑activation only works on the original Dell firmware. (en.wikipedia.org)

About product keys: keys are edition‑specific (Home vs Professional) and media/licence type matters. An XP Home key will not legitimately activate XP Professional. OEM licenses that come preinstalled with a system are generally tied to that machine and are not transferable the way a retail license is. (en.wikipedia.org)

If you have a Dell CD but no key (the scenario): first check the laptop for the Certificate of Authenticity (COA) sticker (often under the battery or on the case). If the old machine still boots you can extract the installed key, but be cautious — key‑finder tools often reveal the manufacturer’s OEM/master key rather than a transferable retail key, and that may not work on a different PC. If the COA is lost, contact Dell for recovery options or use properly licensed retail/system‑builder media. (support.microsoft.com)

If the install runs but you have no network/USB drivers (as warned), use another PC to download drivers and transfer them by USB:

  • In Device Manager on the XP install, open the unknown device, Details tab → Hardware Ids.
  • Note the VEN/DEV strings and search the vendor or PCI ID databases to identify the part.
  • Download the matching driver from the motherboard or NIC vendor and install offline. (learn.microsoft.com)

Recommendation: for reliability and fewer licence headaches, use retail installation media with its matching key, or run legacy XP apps inside a VM on Windows 7/10. Also remember Windows XP reached end of support years ago; running it online carries security risks. (en.wikipedia.org)

So as you may be aware, it is possible to automate the installation of a Windows operating system. Basically the "Dell" installation CD is really just Windows XP + specific device drivers embedded into the install process and possibly other Dell specific items. I suspect that you should be able to get through the installation minus device drivers.

With regard to the keys, Home edition and professional will have different keys. otherwise, people would buy the home edition and use the key on professional.

The answer is "it depends". Most OEM Windows installations will check to see if the hardware is supported - device drivers have little to do with it. I know that HP Windows installation discs won't work with non-HP gear - I've tried it. I would suspect that Dell versions are similar in behavior. A purchased retail version will install on any compatible hardware, so you may have to reconcile yourself with purchasing a retail version, or switch to Linux which is free... :-)

Like they've said, the biggest issue will probably only be the drivers. In the worst case, you won't have a working ethernet driver. This is a bad thing because you cannot automate driver updates without this... (You need the internet to find drivers.) I have had this problem many times installing new OSs. If this ends up being the case, you can find the ethernet card model by right clicking my computer and selecting properties, then hardware. From there, you can look up the driver for the OS for your specific card. If you end up not having an ethernet card compatibility issue then finding drivers for the rest of the hardware will be simple. Just go into control panel, classic view, add hardware, wait for it to finish scanning, click yes already attached (or something like that) and select the hardware you want to find a driver for. This can be tedious because it only allows you to install one driver at a time. The most serious issues will probably be not having usb mouse/keyboard connection, in which case you'll need to use a classic non-usb keyboard/mouse initially, and the video card (this will be apparent if your screen is set to 600 x 800 or the like). Again use add hardware in control panel to find the drivers! Any help needed, let us know!

I have similar issue with the post discused above. I have new custom built computer and my son installed window 7, most of my really old programs are for window xp, so we bought another internal hard drive. Our plan was to install Xp on 2nd internal hard drive and then install my old program like old PhotoShop, Illustration and Singer Futura Embriodery etc.,

We installed the Window XP Pro from the CD I got from Dell laptop I bought 7 years ago. I didn't get the product key from the CD because back then the computer was pre-installed with Window XP Pro, Dell didn't include the CD with the laptop. I had to specifically request Dell to send me Window XP Pro CD as back up. I'm not sure the what the problem is - wether I don't have the product key for Window XP Pro or the Dell driver CD, we can't set up internet.

If I get a OEM XP Pro, would that work for my new computer?

The trouble with OEM licenses, is they also activate via hardware id's. Each component inside your computer has a hardware id so windows can identify it, and sometimes, definately with windows vista/7 but i think it includes xp, if the hardware is too different from what the OEM key specifies, then it may not allow you to activate.
