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 made, depending on whether setup is installing on top of and can understand a prior installation.

A friend bought this dead HP pavilion 364n desktop for pennies(I don't buy used computers) and asked me to help fix it. It has product key for Windows XP Home Edition label attached to the case.I replaced the PSU, then I was able to boot the computer. However, I can't do anything with the guest account and the admin pw is unknown. I will like to do Recovery. The Recovery option F10 during booting process is not responding though I see the recovery partition present. What are my options? If I call microsoft and give the product key will they send me win xp cd? Or is there any other means to access recovery partition?

Hey there! I was wondering if you had any thoughts... My Sony desktop was running an antivirus software program when XP Media Edition decided to automagically reboot. When the desktop came back around, I tried to log in. When I went to log in, the computer said, "welcome" and then "logging off" and took me back to the user screen. I've tried entering all of the accounts (range from user to admin) and haven't been able to get in.

Is there a way for me to reinstall XP - Media Edition on the computer without losing all of my information and applications? Or, Just putting regular XP - SP3 on it? I've looked it around but haven't found any real help.... thanks.
