Cannot install operating system on my pc

You'll have to obtain new OS software. The reset disks assume that the original OS is still installed, and help to restore it to factory defaults (i.e. exactly how it was when you purchased it.) If you are looking for Windows, you'll have to visit a local store to purchase a new copy (generally office supply stores, or PC stores carry them.) Alternatively you can find other free Operating systems online using another computer, and create an install disk to start over. (Ubuntu is very popular and easy to use.)

Doing a wipe like that erases EVERYTHING so the computer has nothing to load. The only fix is to get new OS installation software and re-install.

How to Reload Windows XP Without Removing Files Deleting system files, modifying the registry and installing incompatible drivers to Windows XP can damage the integrity of the operating system, rendering it inoperable. Virus infections are often responsible for making the aforementioned changes to a system, but employees who have administrative access to the workstation can make deleterious modifications to the OS as well. Reinstalling Windows XP can repair the OS, but if work-related files are stored to the system partition, all of the data will be erased during the installation process. To reload Windows XP without losing files, you can perform an in-place upgrade, also known as a repair installation.

Step 1 Insert the Windows XP CD into the optical drive and then press "Ctrl-Alt-Del" to restart the computer. Step 2Press any key when prompted to load the contents of the disc. Press "Enter" on the Welcome to Setup screen.
Step 3 Read the license agreement, pressing "PgDn" to scroll down the page. Press "F8" to agree to the terms. The CD will search for previous installations of Windows XP. Step 4
Press "R" to repair the selected operating system. The disc will begin reinstalling the operating system to the hard drive without affecting personal files. Follow the on-screen prompts to complete the repair installation. Step 5
Log in to Windows XP and sign on to the Internet when installation completes. Click "Start," "All Programs" and then "Windows Update." Step 6
Click "Scan for Updates" to search for applicable service packs and hotfixes to reinstall to the OS. Step 7
Click "Install Now" to bring the in-place upgrade up-to-date.
Things Needed

• Windows XP CD

Tip

• Make sure you have your Windows XP product key (found on the CD cover or on the computer case) available prior to reinstallation.

Warnings

• If possible, back up your files previous to the installation in case something goes awry during the process.
• You will need to reinstall all non-native programs and removable devices after performing an in-place upgrade.

Power on your computer and wait for Windows to fully load.

Click the "Start" button and select "Control Panel."

Click "System and Maintenance," scroll down and click "Administrative Tools."

Double-click "Computer Management." If you are asked for permission to perform the action, click "Continue."

Click "Disk Management" on the sidebar. This will give you an overview of the available disks on your computer.

Right-click the "C" drive and select "Format." Click "OK" and the process will begin.

Once the process is finished, you will be unable to use your computer until the operating system has been re-installed.

To do this, you will need to use a Windows Installation Disc or a USB flash drive containing Windows.

hope this helps

Once you enter the setup and it loads the entire program, then you need to press the R key, which is for repairing the windows installation. This action will take you to the dos mode where further processing will be done. In the dos mode, system will ask you about installation place. Most of the people install their operating system in the C drive, which comes at number 1 option, so you need to press option 1. However, if you have so many partitions or you have installed the operating system then you need to choose the option according to your drive name. Here you need to enter your password as well, but if you have not set any password then you can simply press enter.
*Then there will be a c:\WINDOWS> command in a dos mode where you need to write, "Copy d:\i386\ntldr c:\windows. However, if you have different place of your installed operating system then you will write the address of that drive. This is the whole process and now you can eject the cd and can press exit to restart the system. Now this process will copy the correct NTLDR file from installation disk to your hard drive by making your system in the working condition.

1. If you have the recovery cd, you can just pop-in the CD, select the reformat option and the installation process will continue automatically. Some laptop might have a special partition in the drive contains the operating system, drivers, etc. in case you want to reformat your laptop without the CD.
   
2. Step 2 If you don't have the recovery CD, you usually can request one from the manufacturer. Otherwise, if you want to do a clean install, make sure you download all the drivers for your laptop, this may includes: motherboard, chipset, graphic card, sound card, modem, network card. Once you do that, put in the OS CD and start installing.
   
3. Step 3 If you decided to do a clean install without the recovery CD, it would be best to create partition on your harddrive first, so you can have dedicated partition for operating system and backup. The next time you want to reformat your harddrive, you can just reformat that particular partition ex. C:\
   
4. Step 4 After the reformatting process finished and you have installed a new clean OS. Install drivers one by one and restart when it's required. Try to do it in order from basic function -> secondary ex. motherboard, chipset, graphic, sound, modem, networking, etc.
   
5. Step 5 Install back all programs that you might need. If you already backup the installation programs or have the installation CDs handy, you can do this pretty fast.
   
6. Step 6 Rearrange the look and customize your new operating system, refer to the screenshot you have taken earlier before the reformatting process begin if you want to get the same look and feel.
   

Re-install your OS.  If you still get the OS error, then your hard drive is fu.k.d up, in which you can get a cheap replacement for your machine on e-bay.  Install the OS on the new hard drive and have a good day.

Do it and reply me.

Please go to control panel, click on programs and uninstall the desired one.

Good luck.

You will have to reload OS from startup. System may say OS already exists but you should have th option to continue. Netgear has a problem with their pc card. Recommend you buy another brand like Linksys...

The picture is misleading. Haha anyways, Its really simple to install an operating system. All you need is the installation CD and proper installation hardware such as (DVD, CD, or DVD/CD rom). Along with a hard drive. Now before installing an "O.S" follow these simple steps:

1-make sure its compatible with your motherboard, some motherboards are not compatible with certain versions of O.S.
2- you have to make sure, your processor is capable of the running the O.S you plan on installing.
3- You have to make sure you have enough Ram to run the O.S (the Ram and processor both have to be compatible with the motherboard to begin with).
4-Make sure your Hard drive is capable of supporting the O.S by having sufficient space to satisfy your needs and the O.S itself.

Once you have followed those steps you can follow the on screen process provided by the O.S installation CD.

In your Case this is what you would need.

A motherboard suitable for the processor you wish to use.
16Mb of ram or more (a single 32Mb ram stick should do).
A Hard drive of atleast half a Gig (i would recommend 10Gig or more so you can store more files).
