Considering that the formatting procedure deletes all files and data on the computer, before starting the operations indicated below, I strongly recommend that you perform a backup of your data that may be present on the computer in such a way as to be able to access it always and in any case also at a later time and regardless of whatever happens.
To do this, you just need to save all your data that you consider most important (documents, photos, music, films, etc.) on an external hard drive, a USB stick or DVDs. I explained how to proceed using the functions attached to the same operating system in my tutorial on how to backup Windows 7.
Alternatively, you can do this by turning to third party tools. If you want some advice on which resources to use to make a backup and which steps to take exactly to perform this operation, take a look at my dedicated article, precisely to the backup programs through which I have indicated all those that in my opinion I represent the best software in the category and what needs to be done to be able to make the most of them.
Format Windows 7 PC with the installation DVD
If you want to format Windows 7 PC and you have at your disposal the installation disk of the operating system, the first thing you need to do is to insert the latter into the computer and restart the PC. If you don't have the Windows 7 installation disc but are still interested in installing the operating system on your computer this way, read my guide on how to buy Windows 7 to find out immediately how to find it.
Once you have recovered the Windows 7 disk and once it has been inserted into the PC, wait for the message to appear Press any key to boot from CD-ROM or DVD-ROM ... on the screen and then press any key on your PC keyboard to boot the computer from the Windows 7 disk and not from the system installed on the hard disk. If it doesn't appear, most likely it's because you need to boot from the CD / DVD drive. If you don't know how to do this, you can follow my guide on how to get into the BIOS.
Then wait for the files necessary for the installation of Windows to be loaded and, if necessary, consent to the download from the Internet of any additional files necessary to carry out the formatting procedure. In the screen that is subsequently shown to you, make sure that in correspondence with the items Language to install:, Time format and currency: e Keyboard layout or input method: is selected cityno from the relative menu (and if not, make the necessary changes) and then click first on NEXT and then Install.
At this point, you need to click on the button Custom (expert users) and select the partition where your Windows is currently installed (it should be Disk 0 Partition 1, unless you have no more hard drives or partitions). Then click on the entry Drive options (advanced) located at the bottom right and first click on Format and then OK to format Windows 7 PC.
When the operation is complete (a few seconds should be enough), click on NEXT to start the installation of Windows 7 and wait for the first part of the process to finish. It should take 10-15 minutes after which the computer will restart by itself. After rebooting, do not press any key when the message appears on the screen Press any key to boot from CD-ROM or DVD-ROM ... but wait for the installation of the operating system to complete automatically.
Once the installation procedure is complete, the computer will restart automatically and the initial configuration procedure of Windows 7 will begin. Complete it by typing the username you want to use to access the operating system and the one you want to assign to the computer and click on NEXT. Then specify the password to be associated with the account, type a phrase to use as a suggestion to remember it and click again on the button NEXT I will continue.
Now type the serial code of your copy of Windows in the appropriate text fields and click on NEXT to activate your copy of the system (you must be connected to the Internet). If you don't have the Windows serial at hand, don't worry, you can also skip this step by clicking on the button Ignore and enter the code later, when installation is complete.
Then click first on Use recommended settings to enable all Windows 7 default security systems and then on NEXT to adjust the time settings and then to Home network to set the time and network, then wait a few moments for all settings and configurations to be applied to the system.
At this point you can finally say you are satisfied: you have successfully completed all the procedure by which to format the PC. As a demonstration of this, you will see the Windows 7 desktop appear on your computer screen. There is nothing left to do but install any missing drivers and your favorite programs, then you can start working freely with your brand new operating system.
Format Windows 7 PC without installation DVD
Do you want to format Windows 7 PCs but do not have the operating system installation DVD at your disposal or your computer does not have an optical drive? Don't worry, as I told you at the beginning of the guide, this is still a feasible operation. Just create a USB stick containing the operating system installation files and you're done.
To do this, first get one pendrive of sufficient capacity. Personally I suggest you find one with at least 4 GB of free space. Also make sure that the key to be used is empty or that in any case there are no important files on it because in order to use it you will need to format it.
In addition to a USB stick of sufficient capacity, you need theISO image Windows 7. If you do not know where to find it, I suggest you look for it on sites that allow legal download (to be able to install it you will then need to use your license code). Alternatively, you can create it yourself starting from a computer equipped with a DVD player as I explained to you in my guide on how to extract ISO files from DVDs and CDs.
Then click here to connect to the free application download page Windows 7 USB / DVD Download tool that allows you to transfer Windows installation files from ISO images to USB drives and presses the button download for free placed on the side to start the program download. Once the download is complete, open the installation package Windows7-USB-DVD-Download-Tool-Installer-en-US.exe and click on Run, Then Next, its install and then on Finish to finish the setup.
Then click on the button KATEGORIEN which is located in its main screen to select the Windows ISO image to use to create the Windows 7 bootable USB. Continue by clicking on Next, Then USB Device and finally on Start Copying in order to start copying the files from the ISO image to the USB stick. Then wait for the green progress bar in the program window to reach the 100%.
Once you have copied the ISO image files on the USB stick you can format Windows 7 PC simply by booting the pendrive. To do this on your computer, simply leave the stick plugged into the USB port you inserted it into and restart your PC.
If restarting the Windows 7 PC is normally performed and the system formatting procedure does not start, it is evidently because you must first set the USB port as the primary boot device instead of the computer hard disk or DVD drive. If you don't know how to do it, you can follow the instructions I gave you in my tutorial on how to enter the BIOS that I pointed out a few more lines.
After booting the key, follow the system installation procedure indicated above, when I explained to you how to format Windows 7 PC using the system installation disk. At this point the steps to take are practically the same. Have fun!How to format Windows 7 PC
