Data recovery from system partition

Normally a new hard drive is divided into several logical partitions to treat one disk as if it were multiple disks for the sake of convenience and better performance of the hard drive. Isolated partitions increase data safety as well - if one partition is corrupted data on other partitions remain intact. Traditionally operating system and program files are separated from user files and are usually stored on an independent partition referred to as system partition - Disk C: for Windows, for example. As you buy a new computer with a preinstalled operating system you probably get a hard drive with the only partition which is the system partition where user files, program files and operating system are not separated from each other. Unfortunately, system partition is exposed to impact of viruses, sudden power cuts, software malfunctions, hardware failures and simply accidental deletion of files that may be a good cause for loss of essential information.
If you've accidentally deleted a crucial file from the system partition you should bear in mind one thing - as a partition where constant record is performed system partition features extremely high possibility of deleted files being overwritten. Defragmentation, indexing, background optimization or OS journalizing as well as temporary files of working program result in overwriting of lost files. Thus, there's no time to waste. You should stop working immediately and unplug the working computer without shutting it down. Sad to say, but even immediate stop of all operations doesn't ensure 100% recovery from the system partition after all.
Such negative factors as operating system malfunctions and software or hardware failures may cause damage of the operating system itself. As a result your computer will shut down and won't boot again. Blue screen, repeated system rebooting or no desktop are indicators for a damaged operating system. If the system partition contained nothing more precious than operating system the problem could be simply resolved by operating system re-installation. But, if important files were stored on he system partition or this was the only disk partition the files will be gone for good after operating system installation.
You will certainly find a perfect solution in a reliable data recovery software.
