I have no CD - how do I get at Windows XP setup?

Home » Windows » Windows Installation

Summary: If you don't have your Windows installation CD there are still a few things you can do. If you have an image of your CD, you may be able to do more.

I have no CD - how do I get at Windows XP setup?

I discussed in a prior article what to do if you have no installation CD for Windows XP. But now once you've found your CD image - where's the setup?

What you need will depend on what you're attempting to do.

If you want to make a change to your system configuration - perhaps adding an accessory that you neglected at the original setup - then the place to go is not setup, but the control panel:

  • Start
  • Settings (if you're using classic start menu)
  • Control Panel
  • Add or Remove Programs
  • Add or Remove Windows Components

That will bring up the dialog that's extremely similar to setup in which you can select the optional Windows components to add or remove.

If you're looking to reinstall system files because you suspect corruption what you really need is the System File Checker. This utility validates that all of windows system files are correct and fixes those that are not:

  • Start
  • Run
  • Type: "sfc /scannow" without the quotes followed by Enter

sfc may ask for your installation CD-ROM. (See this article if you don't have one.)

Finally, if you really, honestly and truly want to re-install windows, the first step would be to run your installation CD. If you don't have one, you may have an image of the CD on your hard disk. In the I386 directory are two files:

  • winnt32.exe is the "32 bit" version of the character mode Windows setup. You may be able to run this from within Windows.
  • winnt.exe is the "16 bit" version of the character mode Windows setup. Why a 16 bit version? If you can't run winnt32.exe and are able to boot from an MS-DOS floppy or are able to boot to Win9x DOS mode, then this setup program will work for you.

WARNING: character.exe and winnt32.exe are the "start-from-scratch", "do-it-all-over-setup" programs. Use them only if you want a complete re-install of Windows - possibly losing any prior custom configuration changes you'character made, depending on whether setup is installing on top of and can understand a prior installation.

HOW do you "copy the (XP) CD to your harddrive? It sounds like a good idea, but I don't know how to do it. Is it that ISO thing? I'm not sure what that is either. I used to be a programmer before I retired, but it was mainframe and sometimes these days I'm just lost.

Why is it that years ago they would provide a hard disc of the Windows system...but now they only supply a card with the key code written on it? I would like to get an original hard disc of my operating system - Windows XP home edition. How can I go about getting one without having to go to a computer store or other sales venues and buy one? I've paid for it once when I bought this computer...so why can't I get one free????

You mean a CD, not a "hard disk". A hard disk is what's installed in your computer already.

This is a choice that manufacturer's make to save money. You should contact the manufacturer of your computer and insist that they include a CD of the OS when you purchase your machine.

Hi Leo,
when I try to run the system file checker my system says "windows cannot find sfc/scannow. Make sure...."
I went through START and RUN and followed your instructions. Any ideas?

There needs to be a space between "sfc" and "/scannow".

I was trying to re-install windows xp and it didn't complete. I want to reformat my harddrive and cannot do so because windows setup application temporary files are still in use somewhere and I'm not allowed to delete everything off of my c:\NTFS partition. How do I get rid of these files so I can wipe the slate clean? I have Generic Host Process win32 errors and svchost.exe errors that are haunting me. I have tried everything out on the interenet suggest to remove the errors but nothing works. HELP!!!!

Boot from your Windows installation CD and you can reformat the main drive.
