Windows Hangs at Startup Screen and Safe Mode Fails to Boot
Image via Wikipedia
You might run into several Windows boot issues for the reasons like infected system drivers, virus infection, missing or corrupted Windows system files and others. To help fixing such problems, Windows includes some tools and Recovery Console commands. But if neither of them works, you will need to repair your Windows installation or ultimately, remove it to install a new one. If you experience data loss in such situations, you are suggested to use your backup or scan the disk using a commercial Data Recovery Software.
To illustrate, consider that you use a Windows based computer system. You experience that when you start your computer, it hangs at Windows startup screen and fails to boot. When you try to boot the system in Windows safe boot, it executes the below files and the process halts:
multi(0)disk(0)rdisk(0)partition(1)\WINNT\System32\ntoskrnl.exe
multi(0)disk(0)rdisk(0)partition(1)\WINNT\System32\hal.dll
multi(0)disk(0)rdisk(0)partition(1)\WINNT\System32\BOOTVID.dll
multi(0)disk(0)rdisk(0)partition(1)\WINNT\System32\config\system
Further, when you try to boot the system using Windows boot disk, it gives NTDETECT failure error and you cannot access the data.
Cause
Among other possible reasons, few of them are:
-
One of the primary boot files, like MBR, Boot.ini, is damaged
-
You computer is infected from virus that has replaced the Bootvid.dll file required by Windows to display graphical image
Solution
To solve the existing issue, you can consider applying the following steps:
-
Insert the Windows installation CD and boot the computer using it
-
Press any key when prompted to start from CD
-
Pres ‘R’ to start Recovery Console when the Setup starts
-
Select the target Windows installation
-
Specify the administrator password, if any
-
The command prompt will appear. You can then execute appropriate repair commands like Bootcfg, Fixboot and Fixmbr
-
Type Exit to exit the Recovery Console
If this doesn’t help fixing the described Windows boot problem, try repairing or reinstalling Windows installation. When you perform clean Windows installation, you lose data that can be restored from backup. But if no good backup exists, use an efficient data recovery utility.
Data recovery software are safe tools that are primarily designed to recover lost data from a logically crashed disk. Using high-end scanning algorithms, these tools prove to be reliable and powerful Partition Recovery products.
