Sometimes there may be corrupted system files, but you are left there, trying to work with a barely functioning copy of Windows XP. Maybe all of your programs start too slow and you wish there was a way to make Windows as fast as it used to be. Thankfully, repairing or reinstalling Windows XP is fairly straightforward. Follow these steps for a painless installation. It doesn't matter what version of Windows XP you have.
Steps
Method 1 of 3: Repair the Installation
Step 1. Insert the Windows XP CD into your computer
If you don't have a copy of the CD, contact your computer manufacturer for a replacement or to download an *.iso file from the Internet that you can burn onto a blank CD. Beware of viruses and know that you will still need to enter the Product Key, the valid product code for installation.
Step 2. Make a note of your Product Key
It is helpful to have this information handy before starting the installation process. This key is a 25-character code that you must enter in order to install Windows. It can usually be found in a couple of different places:
-
Written on the plastic container of your Windows XP CD, usually on the back.
- Attached to your computer on a label. If there is a desktop, it is usually located on the back of the tower. For a laptop, it's on the bottom.
Step 3. Restart your computer
Make sure the Windows XP CD is inserted. The computer must be set to boot from the CD-ROM drive. To do this, you will need to enter the BIOS setup.
-
To enter the BIOS, press the setup button as soon as the computer manufacturer logo appears. The key differs for different manufacturers, but is generally F2, F10, F12, or DEL. The correct key name will be displayed on the screen as well as the logo itself.
-
Once you are in the BIOS, go to the boot menu. Set the CD-ROM drive as the first Boot Device. Depending on your BIOS and setting, this might also be called a DVD drive, optical drive, or CD / DVD drive.
-
Save your changes and exit the BIOS. This will cause the computer to restart.
Step 4. Start the installation
Once the manufacturer screen disappears, a message will appear saying "Press any key to boot from CD". Press any key on your keyboard to start the installation process. If you don't press a key, the computer boots from the hard drive as usual.
Step 5. Setup will be loaded
Windows must load the drivers to start the installation process. This may take a few moments. Once it is complete, you will be greeted by the Welcome Screen. Press ENTER to initiate an installation repair. Do not enter the Recovery Console.
Step 6. Read the contract
Once the license agreement is confirmed, press F8 to accept and continue. The installation will load a list of your different options available for Windows XP. Most users will only see one entry listed here.
Step 7. Select "Previous Installation"
If you only have one installation, it will automatically be highlighted. Press R to start the repair process. Windows will start copying files and then restart your computer automatically. Then the repair installation will begin.
-
You will be asked to confirm the date and time, as well as you will have to answer some other fundamental questions. For most cases, the default option is acceptable.
Step 8. Enter the product key
Towards the end of the installation, you will be asked to enter your product key. Windows will check for a valid key before proceeding.
-
After installation, you will need to authorize your copy of Windows online or over the phone. The Product Activation Wizard will appear when you access your newly repaired copy. If you have an internet connection, then you should be able to authenticate the copy by clicking a button.
Step 9. Check your schedules
Once the installation is complete, you will be taken to your repaired installation of Windows. Since some system files have been replaced, some of your installed programs may not work and may need to be reinstalled.
-
Some of your devices may need to reinstall the drivers. To see which devices are not installed correctly, open the Start Menu and right click on My Computer. Select the Hardware tab and then click on Device Manager. If there are devices with a yellow exclamation point, you need to reinstall their driver.
-
Personal data and documents should be intact after a repair installation. Make sure everything is where it should be.
Method 2 of 3: Format and Install
Step 1. Backup your data
Formatting and reinstalling Windows will automatically clean your hard drive. Be absolutely sure that you have backup copies of your important files before you begin. Pictures, movies, documents and music will all be deleted.
Step 2. Insert the Windows CD
Make a note of your Windows product key, as it is needed during installation. Boot, the very first boot phase, from the Windows CD to start the installation program.
Details for this step can be found in steps 1 through 4 in the first section of this guide
Step 3. The configuration will be loaded
Windows loads the drivers for the setup program. Once this is complete, press ENTER on the Welcome Screen to begin the installation. Do not enter the recovery console.
Step 4. Read the license agreements carefully
Once you have read the agreement, press F8 to continue the installation process. The installation will load a list of your different options available for Windows XP. Press ESC to continue with a fresh installation.
Step 5. Delete the partition
You should see a list of your hard drive partitions. These are drives C and D: the letters that distinguish them depend on how the operating system was installed.
-
This is the last chance to reboot and back up any files you have forgotten. Once the partition is deleted, the data is lost.
-
Highlight the partition that contains Windows. This is commonly partition C. Press D to delete the partition. Confirm that you want to delete the partition by pressing ENTER.
-
It will be possible to go back. To confirm that you really want to delete the partition, press L.
Step 6. Create a new partition
Select the unpartitioned space. Press C to create a new partition. Enter the maximum possible size and press ENTER.
-
You can create a lowercase partition if you want to create other partitions on your hard drive later, through Windows. There are several reasons for wanting to do this, but for most users it should be okay to just create the largest possible partition.
Step 7. Windows installation begins
Once the partition is created, highlight it and press ENTER to start the Windows installation. You will be asked to format the partition. Select "Format Partition Using NTFS File System". Choose NTFS over FAT, as NTFS is much more stable for Windows.
-
Formatting will begin. This process could take up to several hours, depending on the size and speed of your hard drive, but for most users it will take a few minutes.
-
After formatting, Windows will copy the files it needs for the installation process. This will take a few minutes and no user interaction.
Step 8. Windows will begin the installation
This is a mostly automated process that requires the user to enter some data in a few places. The first option that comes up is to change the default language and region. If the settings are not correct for your region, click CUSTOMIZE. Once the settings are correct, click NEXT to continue.
-
When prompted, type your name and organization. These will be used when the documents are encrypted and can be changed later from the Windows settings.
Step 9. Enter the product key
At this time, you will be asked to enter your 25-digit product code. You won't be prompted yet, though, at least for now, if you're installing via a Windows XP SP 3 disc.
Step 10. Enter the computer name
This is the name that will appear on the network to describe your computer. Windows automatically generates a name for you, although you are free to change to whatever you prefer.
-
For XP Professional, you will be prompted for an Administrator password which will be used to log into the master account.
Step 11. Set the correct date and time
At this point you will see a calendar and a clock that can be adjusted to the specific time of your geographic area. You can also select the correct time zone for your region.
Step 12. Select Networks
You will be asked if you want to install Typical or Custom network settings. For almost all users, Tipica is the right choice. If you are installing in a corporate environment, check with your system administrator first.
-
When asked to enter a workgroup, most users want to select the first option and leave the workgroup label as the default. If you are in the company, you may need to specify a domain. Again, contact the administrator.
Step 13. Windows will finish the installation
This will take several minutes with no user input required. Once finished, your PC will automatically restart and load Windows XP.
-
If you had to change the BIOS to boot from CD, you will probably see the "Press any key to boot from CD" option again. Do not press any key, but wait for it to pass the screen. The computer will continue booting from the hard drive and finish installing Windows.
Step 14. Select OK to adjust the screen resolution
Windows will try to automatically change the screen size to make it easier to read. Once the screen is reset, you will be asked if the new text box can be read. If possible, click OK to continue. If this is not possible, then press CANCEL or simply wait 20 seconds to restore the original screen settings.
Step 15. Select NEXT to proceed with the installation
The Microsoft Windows Welcome Screen will appear as soon as any screen changes have been made. This process will only take a couple of minutes.
-
Windows will attempt to verify network connectivity. If you are thinking of fixing it later, you can skip this screen.
-
Windows will now ask you if you are connecting to the Internet through a local or home network or if you are connected directly. If you are using a router for your network, select the first option. If the modem is connected directly to the computer, you can select the second option.
-
You are given the option to register your product with Microsoft. Whether or not this is up to you, it's not necessary to use Windows.
Step 16. Enter the names of the users
In this step, you can create separate logins for each of the users on the computer. At least one name must be entered. Up to five users can be entered on this screen, but more can be entered through the Control Panel after installation.
-
After entering the names, click DONE to complete the installation. Windows will run for a few moments and then you will be greeted by your new desktop.
Step 17. Run Windows Update
The installation is complete, but it is recommended that you run Windows Update as soon as possible. This program will download the latest system updates from Microsoft. These updates, such as fixing system vulnerabilities and stability issues, are very important,.
Step 18. Install your drivers
Chances are, you need to reinstall the drivers now that your computer has been formatted. Depending on the devices that are connected to the computer, they could include the video card, the modem or network card, audio and more.
These drivers can be found on the discs distributed with your computer and can also be downloaded from their respective manufacturers' websites
Method 3 of 3: CD-less Installation
Step 1. Installation from the recovery partition
Many computer manufacturers sell their computers with a partition on the hard drive that contains the Windows installation files. To access it, you need to boot the recovery partition.
-
The most common key to enter the partition is F11. However, this key will appear under the manufacturer's logo immediately after starting the computer.
-
The sequences for starting the recovery partition vary from manufacturer to manufacturer. Follow the on-screen steps to enter the Windows installer. Once the installation has begun, follow the steps described in the section above, starting with step 3.
Step 2. Installation from within Windows
You will need to use a file called winnt32.exe. This file is a Windows installer that can be run within Windows XP itself. To find it, open the Start menu and click Search. From the left frame, select "All files and folders". Enter winnt32.exe in the search box.
-
Launching the winnt32.exe file will restart the computer into the Windows installation. From this point on, follow step 3 of the previous section. You will still need to enter a valid product key. The data will be deleted as it would through a normal installation.
