In Microsoft Windows operating system, boot process is handled by various components, such as boot loader and Boot.ini file. The Boot.ini file contains boot configuration settings of Windows operating system. Sometimes, you may not be able to boot your Windows computer if your system use “multi()” syntax in Boot.ini file. The problem also occurs if first sector of boot partition is 4 GB or large. In such situations, you can not access the files stored on your Windows hard drive. This behavior leads to critical file loss situations and requires file recovery.
