Your system does not boot, and you are worried about the important business and personal files saved in the hard drive? If that is the reason for your worry, then you are among millions of users who encounter such situations on daily basis.

Most of these users do not know how to get rid of a boot error message, and thus perform a clean reinstall of their operating system and restore data from an updated backup, thereby wasting a lot of time and energy. Further, in case the backup is insufficient or does not solve the purpose, they are not left with any option. However, a far easier and simpler option is available for such users. They can perform Data Recovery by using a third-party recovery application.

While there can be numerous reasons for a Windows boot error message, one of the most common is corruption of a 'Halmacpi.dll' file. This file is required at the time of booting and helps the desktop applications in accessing the hardware information. Corruption in this file stops the boot process in between and displays a large rectangular box with the below error message:

"login process initialization failure"

Furthermore, when a user tries to perform a system restore using 'Last Known Good Configuration' option, s/he might encounter another error message:

"boot critical file C:\windows\system32\Halmacpi.dll is corrupt or missing"

After any of the above error messages pops up, the data saved in the hard drive can not be accessed.

Resolution:

To resolve the above error message and to access the hard drive data, a Windows user needs to take underneath actions:

1. Use 'Startup Repair' option to solve boot issues.

2. Use 'sfc/scannow' option to repair the corrupted file.

3. In case, both the above resolutions fail to master the above error messages, then s/he will need to perform a fresh reinstall of Windows operating system. Once the re-installation process is complete, then restore the data from an updated backup.

4. However, the restoration process might fail in case the user has not created any backup. To recover data in such scenarios, the user needs to opt for a commercial Data Recovery Software. Such Data Recovery Tools use effective recovery techniques to recover lost data after re-installation of Windows operating system.

Windows Data Recovery provides absolute recovery of deleted files and folders post re-installation or any other logical corruption scenario. With recovery supported from NTFS, NTFS5, FAT12, FAT16, FAT32, and VFAT file systems hard drives, the Data Recovery Software can be installed on Windows 7, Vista, 2003, XP, and 2000.
