First, you need to determine if there is a recovery tool in your computer. This set of recovery tools will help you bring your computer to its original state from the manufacturer and save a lot of time reinstalling as new.
If you are using a Windows integrated machine (typically a Laptop), then it definitely owns a hidden partition in the hard drive. This partition stores the information needed to be able to recover your hard drive in possible conditions. But if your machine is several years old, the recovery tool kit installed on a CD or DVD is a better choice. Look for the discs that come with the device at the time of purchase, maybe something worth paying attention to. Also, learn the machine's instructions to see if they have a built-in partition to restore your computer to, and if so, how to access that partition.
If you upgrade the operating system, for example from WinXP SP1 to XP SP2, the upgrade disk is a recovery tool. In case you most need to reinstall the machine without any recovery tools, there is no hidden partition at all, and you are not exactly a deep understanding of the computer, then Please contact the place of purchase, or manufacturer.
Backup all problems
Reinstalling Windows is not done. No matter how much data you have preserved, you will still have to install a batch of additional software such as documents, spreadsheets or drivers because almost all of these " things " can be default install on drive C .
So why not create a backup for what you need? Ghost back to the computer when it was just installed is a good idea. This job means, you will create a perfect copy from what you have on your computer, whether it is . junk files at the time you create. Later if there is a problem, you just need to restore it all back from the time you created the copy image. However, Ghost also means that the documents you are using from the time of creating the copy file until the machine has problems will no longer exist. Therefore, note Ghost again either at the time of reinstalling the machine, or the time when you really need the data of some time.
For important documents that you cannot store on the Internet for security reasons, you can create a separate partition on your computer for later recovery. The second way is to find a portable storage device, copy the data through it to protect what you need.
Install Windows
A few notes when you reinstall the device. That's if you just overwrite the old operating system without installing a new one, many of the old operating system's junk files still exist. Use specialized software like Revo Uninstall to clean it. Sometimes what you see is not a junk file, but files that the system automatically backs up if it finds it necessary. For example, in Windows 7, you do not install completely but install overwrite, then in the partition to install the win, next to the Windows folder of the new system will have a folder right next to windows.old, and in it are chapters file or data file that Windows has backed up.
Another thing is that when you set up new support software programs, install each program without going to the health machine to install 4 5 at the same time fast. And if it requires rebooting the system, follow it without thinking. This enables programs to run smoothly and ' endlessly ' with each other, avoiding malfunctions or conflicts between work, damaging your data.
After successfully reinstalling the device, bring the data that you previously backed up and return to the place you want to pay for easy management and continue your work.
