Others, on the contrary, having acquired a computer with a well-known software product from Microsoft, begin to study how to demolish Windows. So, really, how many people - so many opinions. In this article it will be on how to demolish Windows. By the way, the name for the Windows operating system).
Erase! Can't be left!
The reasons why it becomes necessary to remove Windows can be very different. Let's list the main ones:
- a laptop was purchased with a preinstalled operating system, the version of which does not suit the user. For example, the starting 7, in comparison with the most advanced Ultimate, has a number of limitations that make it less convenient to work with;
- due to malfunction installed system its update is required;
- the license period has ended;
- other reasons.
At the crossroads…
It is known that in order for the ship to arrive at its destination, the captain needs to know his current location on the map, the destination and the route of movement. For completeness, a third point is sometimes mentioned - the source port. This principle is true for almost all situations in life, and the answer to the question of how to demolish Windows is also no exception. You don't need to graduate from academy to delete files from your hard drive. You can demolish Windows in a couple of minutes, the main thing is to choose a method. But it depends on current state and the desired end goal. For example, for some people, a complete reformat is fine. partition hard disk, but such a cardinal method is not suitable for others.
Methodology
So how to demolish Windows? Let's consider the main options.
First. Winchester is divided into several partitions, on one of which the operating system is installed. In this case next steps depend on whether there is system partition files to be saved.
Suppose all necessary information ported to other media. In this case, starting the installation new operating system(both Windows and Linux), to the installer's question about choosing a partition, you must specify the one where the system to be removed is located. Then select the "Format" option. That's all - the partition will be cleaned up, and no trace of the old files will be left. This method not suitable for using hard a disk with a single partition.
The second method assumes that the required data remains and needs to be restored later. This means that when choosing a partition for the system, formatting should not be used. All new Windows versions discovering old installation, will transfer all its files to the Windows.old folder, from where you can copy what you need in the future, and delete the excess with Explorer. Quite a convenient way.
And finally, you can use a special Live-CD (you can download it from torrents). From it you should boot into a simplified operating system and erase all files with an explorer old Windows from the hard disk partition. The required data can be saved. Since not all Live discs work with AHCI mode, then you must first switch the subsystem of the hard drive to IDE (Native) in the BIOS.
As you can see, everything is simple. The main thing is to choose the best option for yourself.
If you purchased a laptop on which the "Seven" is installed, and for some reason it does not suit you, you want to install XP, I will now tell you about how to take Windows 7 off the laptop.
What does that require?
In the case when you previously did not have experience in this matter, it is better to seek help from a professional. As for how to demolish Windows 7 yourself, you will need your laptop with the "Seven" installed; a flash drive with a USB connector, the volume of which must be at least four gigabytes; setting laser disc with the operating system that you are going to install on your computer (in our case, it's XP) and, of course, Internet access. The only thing I want to warn you against is formatting the hard drive. You will need a working computer in order to prepare the installation files new system so don't do that.
Before you demolish Windows
First, make sure that you have required drivers for your hard drive. This is necessary in order to avoid possible problems recognition by the hard drive system. Usually, necessary software is located on the disc in the kit or on the official website. Write down the downloaded firewood on the USB flash drive. Next, download the image of the required disk with the operating system, burn it to a disc. This is done with the help of Nero or Daimon. When the burning is complete, insert our USB flash drive with drivers and reboot the device.
Starting the drive and installing drivers
If you are still interested in how to demolish Windows 7, we continue. When the next launch of the laptop is carried out, press and hold the F8 button. A menu for changing boot device should appear. Select DVD-ROM and start loading from it. Based on the menu prompts, install the hard disk drivers. This is done when the system reports the absence of the device. You just need to specify the path to the flash drive. After your hard drive is identified, look for the partition where your "Seven" is installed. You have to format it to file system NTFS.
Completing the installation
Consider that you have received the answer to your question on how to demolish Windows 7. While your Piggy is being installed, the device will repeatedly perform the reboot process. Don't let this scare you or confuse you. You shouldn't pay attention to it special attention and try to prevent the computer from doing so. When everything is over, your laptop will automatically boot the new operating system from the standard hard drive. And although the system will already be installed, that's not all.
Recognition of all equipment
In order for all the devices that are in the computer to become operational, they must be determined by the system. To do this, visit the website of your device manufacturer and download drivers for each undefined object. Remember that you are now interested in the XP section. That's all. Now you know how to demolish Windows 7. But I still recommend making friends with the "Seven", since this system is more modern and functional.
