In the Windows systems, the boot.ini file is one of the first files that is accessed when the system starts up. The purpose of this file is to notify the system about which operating system is to be boot. So, this is obvious if this file gets damaged then the system gets stuck during the booting operation and the system remains inaccessible. In such cases, you should try to modify the boot.ini file so that you could access the system and save the data. If that is not possible, then there is a serious need to use a third-party data recovery software to perform data recovery.
