When Windows 7 operating system is booted, it goes through few important steps which need proper and systematic working of MBR (Master Boot Record), BIOS (Basic Input/Output System), boot sector and NTDLR file. If any of the above mentioned components are found corrupted or damaged due to incompatible device driver, improper installation or virus infection then the whole booting process will be stopped. The after effect of the corruption or damage of any of the components varies situation to situation, but the most common encountered behavior is the appearance of black screen while booting.
Soon after the appearance of black screen, the saved data of windows becomes inaccessible and in extreme cases it might gets lost as well. To surpass this situation, available backed up data can be a great asset, but in case the backup is not available then the only way by which the data can be recovered is by using any third party Windows 7 Data Recovery software. This software uses its sophisticated and advanced algorithm to scan for the lost data and recovers them back to a safe and secure place from where it can easily be restored and used further.
