This article explains how to reinstall Windows XP without CD on computers that were purchased with pre-loaded Windows XP. The reasons for installation without CD can be anything of the two: you do not have the Windows CD or your CD drive is not functioning.

Computers Purchased with Preloaded Genuine Windows XP

In cases where you purchase a computer with a preloaded Windows XP, you also get a Windows Installation CD in addition to other CDs for drivers and extra stuff. However, most vendors do not ship the CD to save on money. Still, they offer a provision to reinstall Windows XP in case you need it. They save all Windows Installation files to any of the drives on the computer. The same folder will also contain the serial key of the product.

In most cases, you can easily identify the folder containing the Windows Installation files. Open the Start menu and click on Search (Windows key + pressing F). In the search window:

1. Click "All Files and Folders".

2. Type "i386" in the topmost textbox without quotes.

3. Click on "More Advanced Options" and click on the checkbox next to "Search Hidden Files and Folders."

4. Click the Search button to search for the folder where the vendor has kept Windows Installation files.

You may get more than one folders with the name. Open each folder, click UP button in the folder window to go up one level – to the folder containing the i386 folder. Look for the file winnt32.exe. If you can see it, this is the folder containing Windows Installation files. You can also locate the serial key in the same folder. Normally, it is a text file named "key" or "serial."

If you are not able to locate the serial, call your vendor immediately to get the serial key. You may also check out the packaging kit to see if the serial is printed on the box. Once you have the information about the Windows Installation folder and the serial key, I recommend you copy it to a location which you can easily remember.

Now that you know the whereabouts of Windows Installation files and serial key, you are all set to reinstall Windows XP without a CD.

However, simply running the winnt32.exe will not be equivalent to reloading Windows XP. Check out the article How to Reload Windows XP to understand what all will you may lose in case you wish to perform a clean install. Accordingly, backup those files. Once you backup the files you want, double click the file winnt32.exe to initiate reinstalling Windows XP without a CD.

Using Another Computer to Reinstall Windows XP

If your CD drive is not functioning and you need to reinstall Windows XP, you might be in a fix. However, there is a simple alternative. Copy the contents of the CD to a portable device such as an external hard drive or USB drive using another computer where the CD drive is fine. Once done, come back to the computer on which you need to reinstall Windows XP. Create a folder on any drive other than the root drive and transfer the files from the portable device to the folder. Once done, you can launch the Windows installation from the local copy easily.

You may also create a Windows XP network and connect to a computer that has a working CD drive using Ethernet to Ethernet connection. Once you share the CD drive, you can copy the Windows Installation CD contents to your computer's drive and use the local copy to reinstall Windows XP.

Note: Although there is a provision in Windows networks for remote installations, it unfortunately won't support remote Windows XP installation. Remote Installations support Windows 2003 and Windows NT only.

Important: You may wonder what if you download free Windows XP from sites such as piratebay. However, I strongly advise you to refrain from doing so; these are not complete versions, may contain spyware, and may also call for a legal action.

RE: Installing Windows When You Don't Have A CD
This is really good article about installing os without dvd drive. I will prefer to use a pendrive and make it bootable to install the  windows XP or Windows 7 or any other operating system. But you need setting in your BIOS that boot from other devices like pendrive and other.

My dell Brand pc CD ROM not work And other CD ROM not support
Hello, I have a DELL brand Desktop. CD ROM not working and other CD/DVD ROM not support for Boot. How can I install Win Xp? Please help me!

Hi
Please search the computer for Windows XP setup files. They should be on a drive seperate from the system drive (in my opinion). If you can find the folder i386 and it contains a setup.exe file, you can initiate it and see if it is meant for XP. If it is, you can format the drive and install XP. Another option is to get XP on a removable storage and install it after formatting the drive.
It may be difficult to format the drive and you may not be able to install XP unless you remove windows 7. To achieve this, you will also need a XP bootable floppy, if the computer you got in the garage sale has a floppy drive.

Arun

reinstalling XP without CD and illegal windows 7 running now
My family just got a garage sale computer that started with XP and has an illegal windows 7 on it now. Can I reinstall XP without CD. The computer does not have a CD/DVD drive in it.

Hi Justin
You can use the ISO image to boot into XP. However, it may not recognize all the devices attached to your computer. So you will also have to install device drivers once you expand the ISO image. That done, your computer will be ready for use.

Installing XP From an Alternate HDD
Hi Arun,

I'm trying to reinstall Windows XP SP3 on another desktop, but I do not have the CD. I tried the winnt32.exe method, but it told me that the XP version installed was newer than the one on the CD. So I attempted to slipstream SP3 in with a copy of the I386 folder, yet it told me that it can not integrate SP3 with a distribution that already has integrated software updates.

I have a small 8gb internal SATA drive that I am not using, and was wondering if I could use this as a boot device instead for reinstalling XP without the CD? I have a copy of the retail XP CD ISO that a friend made for me using their own installation disk. If I copy the contents of this ISO to the alternate HDD, can I use this as a boot device to reinstall XP on the troubled tower?

Thank you in advance,
Justin

Hi Biswajeet
Try booting into safe mode and see if it loads Windows XP. If you boot into Safe mode, you may try System Restore to see if you can rollback windows to a point where it was working properly.

Hi Harry
I can see only one method as of now. You can create a XP bootable CD at your friends' place or get it from any local tech. Once booted, you can use the XP ISP CD to install the operating system.

HI Ashok
You will need to boot from CD in order to be able to format the C: drive. If you are using a Windows installation CD, it should be able to help you boot from the CD. Change the boot order in BIOS and insert CD into the CD Drive. You should be able to accomplish this. Please let me know if you still face problems.

Hi Kae
I guess you should get your computer checked by some expert - a friend, collegue, or a computer tech. I am sorry I wont be able to assist without having a look at these folders. There should be autorun.exe but using it w/o confirming that its related to WinXP setup may lead to further problems.

If you have the installer in any other form (stored in Hard Disk), you can copy that onto a CD and use it easily.

Hi ABHINASH
If you reinstall Windows, you will lose all the settings. I guess there may be some workaround that could avoid reinstallation. Please give me more details or have the PC checked with a local tech so that the problem is fixed w/o having to reinstall the OS.

Hi Debbie
There is no question of laughing. It is always better to clear doubts rather than going ahead and creating a mess.

Coming to your question, if you have a CD/DVD drive and the product key for Windows XP disk that your friend has, you can always use it to install XP on your computer. You have to put the CD into the CD drive and boot from CD to install the XP. To change the boot order, you need to enter the BIOS by pressing the ESC key while booting.

Also, please remember to backup your data before you install the XP as it will format the HDD. This includes data in My Documents and other places on the C: drive, except the Program Files and Windows Folders. You also need to backup your favorites in IE8 (Use File Menu -> Export).

Hope this helps,

Regards,
Arun

no winnt32.exe
I purchased an HP Pavillion dv5000 from Conn's (BIG mistake there) and need to reinstall XP. I have searched for winnt32.exe via WinAccess and it seems as if there is no winnt32t.exe. I hesitate to take it into Conn's so-called tech department as they will keep it a couple of months (I had to bring my desktop in before).
It seems to me that as I purchased the laptop with the installation, then it should be there. Also, it is out of warranty, and they will charge me for something I should have had in the 1st place.
I MAY have access to an XP disc from a friend who has Windows 7 now. Will I be able to load this XP onto my laptop? I know that is most likely a silly question, but I'm not that knowledgeable when it comes to something like this.
Thanks for any input you can give me, hopefully without laughing yourselves silly.

Hi Keith
There is only one method I can see - to get a boot disk and boot from it. Format the entire system partition. Then proceed to installation. Win XP does not help you create a boot disk. You can however use BartPE.com to create one.

installing xp without disc
hi, found the winnt32 etc and started the process however it stopped stating ' the system on the pc is older than the current system ' asume this means as soon as you upgrade ie service pack 2 i am in trouble - please advis e of way around this. have a pc that i would like to reinstall xp and 'clean' the pc without disc
Arun Kumar, MVP Jul 30, 2010 3:22 AM
Hi Raymen
I can see only one alternative. If you can get an older boot diskette for floppy drive, you can boot from it and format the drive containing your XP SP2. But as you cannot add XP2 directly from DOS, you will have to first install either 95 or 98 and then you can upgrade to XP. This means two installations. Once you have the XP, you can download the SP2 from a third party website. You can get only SP3 from Microsoft Windows Update site.

Reinstall XP on SP2 machine
Hi,

I'd like to reinstall a windows xp sp2 machine. All I have is a xp cd-rom(without any SP) and my cd-rom is not bootable(The BIOS is pretty old, can't support CD-ROM boot up)

So I turned on the computer and login to current xp sp2 system and tried to launch the CD to re-install. But the setup program pop up a window told me that my current running xp sp2 is more update than the CD-ROM. So the installtion had to be stop. Is there any way to solve it? Thanks!

Hi Corey
I think you should contact the vendor of the machine to confirm that the code you are using is for Windows. Normally, the Windows key is printed on the CD cover or if the vendor dumps it on the Hard drive, s/he would provide it as a text file in the dump folder.

Reinstall Windows XP
Tried to reinstall Windows Pro XP with a disk I had from another machine. I have two seperate Product Keys, so I didn't think it would matter. Now the machine loads up fine until it gets to product key. I key in the product key and it tells me its invalid. I know it isn't. It's on the sticker on the side of the machine and has been since we bought it. What is wrong?

Hi Sean
It should be, if you are using the same CD that you used to install XP before. Usually, the serial number is printed on the CD/CD case.

An OS should be reinstalled only if you find that it is not working properly. Coming to computer slowdown, it can be too many issues:

Checkout your startup programs and eliminate the unwanted (Type MSCOFIG in the RUN text box. You will get a dialog showing startup programs; Remove the ones you do not want and reboot. A screen will appear. Select "Do not show this dialog again" option.)

Use a registry cleaner and computer cleaners to clean out the junk in your computer. I suggest you download the free CCleaner or the free Comodo System Cleaner. I use both in conjunction to make sure I do not have any junk on my computer. You can also use any better cleaner if you know one.


Coming to making screen smaller in the IE8, you cannot make the screen smaller (you can do so by going to Control Panel -> Display options and increasing the resolution of screen). For IE8, you can change the size of fonts (View menu -> Text Size).

Please let me know if this helped.

Arun Kumar, MVP Jul 2, 2010 3:20 PM
Hi Joe
If you cannot see the file, the Vendor did not place any installation files in your computer. In this case you will need a Windows CD or a Windows Installation Flash Drive to install the OS. I suggest you to contact the person who sold you the computer.
