OT-ish: OS clean-install on pre-fab computers?

Soniclight wrote on 7/25/2010, 5:41 PM
Before I get to that question per se, here is the situation:

I gave a close friend my old Pentium 4 years ago to close friend of mine who lives on a limited disability income. It's been a work horse but at 10 years old, it's dying, so I need to get him a new one -- but something simple and cheap (under USD $400):

He only uses it for Net surfing, email and such. No multimedia editing, etc. - at most maybe some word-processing at some point. Even a dual-core isn't that important.

What I've seen out there on the Net is those compact mini and slim computers in the price range -- but it seems wiser to get a standard/regular size PC for it's more user-friendly in terms of cards, peripherals, replacing parts, etc. (I'm his tech guy, too.)

I built my last computer myself and the Pentium 4 was a local off-brand so I've never dealt with pre-installed operating systems on Dells, Compaq, etc. -- the latter being the simplest way to get such a basic computer.

So here is why I wish to know if one can clean-install an OS on such prefabs:

For various reasons, we want to stick to XP and upgrade to Win7 a few years from now. So let's say I find a great deal on a Dell, Compaq or other name-brand and it has Win7. I want to be able to wipe the drive and install his XP Home.

So:

Q: Would such a pre-fab computer let me do that -- or does Microsoft have some proprietary deal with such companies whereby that only the Dell or Compaq or whatever bundled OS will work on that particular machine? I.e. the OS disk that comes with the computer is the only one that will work with that particular system?

Basic logic tells me that I should be able to install any drive with whatever OS I want on one of these but maybe there is some mobo or bios thing that doesn't allow one to that.

Thanks for your input.

I have purchased a couple of my computers, but built most of them. Of the purchased PC's are a few Sony Laptops, an HP Quad-core desktop and an eMachines PC. I've never left the pre-installed O/S on mine for long - preferring to install a clean version of the O/S.

My experience has been the other way. The install/restore disc that comes with an OEM system will only install on that model, but a generic OS from install from Microsoft should install on any system.

Generally i haven't had any problem with the OS that's preinstalled. The problems are all the free "extras" they give you. Lots of systems come preinstalled with several antivirus packages already running, and some of these are very difficult to get rid of. Generally nothing that's included is useful and most of it is harmful. You can pick through them and delete them yourself, but it's time consuming and involves a lot of registry cleaning. Once that's done though the base OS is usually fine.

If you have a generic install disc then by all means uses this as it's faster and cleaner. However, you'll have to have an install key. The one that came with the OEM system won't work with the generic install. Sadly this is a true pity and i think could be cause for a class action suit against Microsoft someday. Since you're replacing the preinstalled OS with an equivalent one you're still meeting the "one machine : one license" terms.

Thanks for replies though they seem to somewhat tell opposing stories of what one can do.
So what caught my eye was the potential no-go:

(Chienworks said)

Hmm... # 1. "Install key" being different from serial number, I assume -- so some shorter alphanumeric number - i.e. printed on the disk's envelope (or sticker on it) or green original Quick Start pamphlet the XP Home came with? I'll have to call my friend to find out what I had given him with the system.

Hmm... # 2: So does this mean that the mobo and/or bios on a Dell or Compaq or Lenovo or whatever would lock out the installation of the generic XP OS on the pre-fab drive or new/different drive or both -- even if I find the install key for said XP?

Alternate (probably not feasible--or legal?) solution:

--- What if one just pulls out the system drive out of old computer and puts it into new? Different hardware configuration for sure, but would the system update its hardware profile and install what was needed or prompt for one to do so on its own -- or simply not work?

I'm somewhat hyper-ethical when it comes to legal stuff, so I don't want to cross any lines but I would like to salvage a perfectly good OS if I can too.

Here is another option to consider ... re-furbished computers.

Here are a few that come with XP installed (some have recovery CD as well)

I do the same. The factory version is always loaded with so much junk that it takes too long to weed it all out.
The main "gotcha" I can think of is that the pre-installed computers often have oddball hardware which requires oddball drivers not widely available. So, before doing the clean OS install, make sure to get all necessary drivers.

I must be the odd man out.
PC I'm typing this on came with Win 7/64 Pro on it. It was not preinstalled as such. I had to through the installation procedure from the install image. That included the option to install whatever stuff was included in the deal. I installed most of it except for Office Home and the antivirus software . I then installed Office 2010 Pro and Kaspersky. It's been running like a dream ever since and I have to say I'm pretty impressed with Win 7.

Same deal with the bargain Dell laptop I bought for the better half. Went through all the installation of Win XP that was on the HDD and as the deal included a free upgrade to Win 7 applied online to Dell and had the disk arrive by courier a couple of days later and upgraded to Win 7. No real dramas with that either.

That said I have one full retail licenced copy of Win XP that I've installed and authenticated on several machines. All of them at some time had WinXP OEM installed so I wasn't breaking the intent of the licence.

Simply taking a HDD out of one PC and pluging into to another is not likely to work. Windows may not have installed components needed in the new PC or may have installed the wrong ones for that PC. The other issue is authentication is tied to the network controller's ID.

My best suggestion. Buy a cheap Dell, they have some great bargains at the moment. Run with whatever comes with it. No problems then with warranty etc. Dell don't seem to put oodles of crud on their systems anymore. I got PowerDVD and a few other usefull / fun utilities with this one. Seriously if it comes with Win 7 I cannot think of any reason to go back to XP. Nothing against XP, but Win 7 just works. It's a bit more in your face about security but that's not a bad thing.

Depending on what is on the current disk you are thinking of moving, you may or may not be able to pull it off (moving the disk to the new machine). If it is an OEM version that is installed, you probably can't make it work in the new machine. If it was a clean install of a retail version, you may be able to pull it off.

The following link has information on how to install a new motherboard in a computer already running windows XP (note OEM versions can not do this according to the EULA)

There are other links out there too, but this is the one I had handy and will give you some ideas.

Microsoft calls it an "install key" or "CD key", not a serial number. But in the end they're the same thing.

"Hmm... # 2: So does this mean that the mobo and/or bios on a Dell or Compaq or Lenovo or whatever would lock out the installation of the generic XP OS on the pre-fab drive or new/different drive or both -- even if I find the install key for said XP?"

Other way around. The install/recover disc that comes with an OEM machine will look for a specific hardware ID so it can only be installed on the models it ships with. However, a generic install CD should work with any hardware.

OK, I feel I've got a good sense of it all now. As usual, I'm heartened by the useful and intelligent responses. You people are great :)
Thanks again. NRN.
