Windows 7 Release Candidate (RC) is a test-version of Windows 7, the latest release in family of Windows operating systems by Microsoft. When you use it, the problems encountered are recorded and sent to Microsoft for making desired changes. A Windows 7 RC based computer system might fail to boot for several reasons and leave your data completely inaccessible. Among other reasons, you might experience Windows 7 boot issues after installing test updates. However, to restore the data thus lost, you should use the last good backup. On occasion, restoring from backup might not work as it is incomplete or damaged. So, to cope with such problems, it is suggested to use a data recovery software that supports Win 7 RC and allows perfect recovery of lost data.
For instance, suppose that you use a Win 7 RC based computer system. You install few test updates for Windows 7 RC (for example, KB970421 or KB970424), After this, when you try to boot the computer, it goes to ‘Startup Repair’ and gives the below error message on screen:
“missing or corrupt ndis.sys”
You cannot access the data stored thereafter.
Cause
The test updates corrupted Windows 7 RC installation. One or more Windows system files are corrupted.
Solution
Following are the solutions that you need to consider to fix the discussed issue:
-
Try to boot the computer is Safe Mode. If this works, you can start command prompt as an administrator to run sfc /scannow command. The command can repair and fix system file corruption issues.
-
If this fails and the problem persists, you need to perform a clean re-installation of operating system. Since the process deletes all the existing files and folders of primary partition, you should use your backup to restore them.
On occasion, you cannot restore from the available backup. Such situations necessitate you to use an effective data recovery utility to recover seemingly irrecoverable data. data recovery software are high-end applications based on the fact that data once deleted can be recovered until overwritten. These tools serve as suitable partition recovery products with advanced features and options.
