There may be several reasons of reinstalling your Windows like you want to upgrade your version of Windows, or your machine went wonky, etc. Some of the people decide to reinstall their OS to get rid of usual or unusual glitches of the machine. Many of the users fall in a situation that they lose their files when they chose to reinstall Windows from scratch on a new partition. If you also have lost your file while reinstalling Windows, you can recover your lost data from the help of data recovery tools, but before heading towards downloading the tool, there is a need to know what happens when you reinstall Windows.


Windows Refresh or New Installation

There are many methods to install Windows over your current installation. If you choose to refresh (or repair) existing OS, it is a non-destructive process generally and it will not erase or delete your files in any way. In broader terms, if you are refreshing or repairing exactly the same version of Windows that you have now, then only this method doesn’t affect your files stored on the machine. Means, you can’t refresh a 32-bit Windows 7 with a 64-bit version of the same Windows 7.

However, sometimes you may upgrade your Windows installation to a new OS if your system follows the defined specifications and configurations. If you install a 64-bit OS over 32-bit Windows, it will either boot side by side with the old 32-bit version, or performing a fresh install will potentially wipe your data. Although Microsoft notifies you many times before actually reformatting existing volumes or deleting partitions, but users avoid these warning as they are in hurry of reaching multi-page End User License Agreements and reinstalling their version of Windows.

How to Recover Data After Reinstalling Windows

To deal with the situation, the first you need to do is shut down your machine and take the disk out because it is not safe to recover on the same disk that is running Windows. In this situation, you need another computer to connect the disk to as a slave.  If you don’t have another computer, you can boot from a USB flash drive, which is effectively the same (in this situation, there should be a data recovery tool stored on that same USB flash drive). If you have another computer, take your disk out and connect it to a PC running its own copy of Windows.

Selecting a Data Recovery Tool

If you have lost your files after reinstalling the operating system, a simple undelete tool may not be able of recovering the lost data because most undelete utilities will look up records in the file system to find the traces of folders and files which are marked as deleted. And after reinstall Windows, the original file system is pretty much gone and as a result, nothing is left for traditional undelete tools to look up.

In this situation a universal tool like defencebyte backup software can help you in recovering deleted data. This tool will analyze your physical hard drive to find the original partitions and file systems that the old copy of Windows was using. If it finds such partitions are discovered, it then adds to the list of volumes available for recovery.

And if no trace of old partitions or files systems is discovered, you can still recover many types of information such as documents (*.doc/*.docx, *.xls/*.xlsx, and several dozen other formats), pictures, videos, emails, calendars, databases, compressed archives and a lot of other information.

Like every other suite of software application, Windows also is not error free and has some flaws. Although Microsoft always try to fix the issue as soon as it is identified. If you are a Windows user and facing any problem, you can seek the assistance of certified technicians at TechNetOnlines at an affordable cost if you want to reinstall Windows 7.
