Troubleshooting Windows Installation

Today in this post we will be discussing about the troubleshooting most common problems that can occur while you try to install a fresh Windows OS, it maybe any of 7 or 8 or 10. So let's take a close look before you think of taking any further step to buy a new hard drive.

Common causes of OS failure

1) Corrupt NTLDR
Corrupt NTLDR message is one that is very common on older versions of Windows such as the Windows XP operating system. NTLDR files are very crucial and highly important boot files for one's computer and their deletion means that one's system will not start. To deal with this, one should start the computer with a boot disk so that one can copy back the deleted files onto the hard drive, then carry out a system restart and the Windows operating system begins to run.


2) Corrupt Boot.ini
The corrupt operating system message mainly appears in instances where oneis trying to access a drive that is configured as a boot device but with the absence of a boot loader in one's computer. With such an error message, one may need to get into the recovery console environment and run the check disk command to check if the OS is in one's computer. In other case, one should only carry out updates on the Master Boot Record and everything gets right on track.


3) Corrupt operating system
When the operating system isn't installed or it is corrupted, then this message appears and this message indicated that one has to do something about the installation of new windows.


4) Corrupt GI
The corrupt graphical interface normally results into a dark screen that appears in instances where Windows does not start up. User interfaces and login screens are absent and therefore there could be a problem with the video system. One should try to update the video driver or start the system in graphics mode for lower resolution graphics so as to get to a point of loading the new drivers.


5) Graphical Interface fails to load
The graphical interface probably fails to load due to the absence of the necessary graphics drivers or a problem with the video hardware. In such a case, try updating the video drivers or install a new version of the drivers.

Steps to install fresh copy of OS

3) Windows installation dialog box
Select the "Repair now" option in the box and select command prompt to repair pc. Cmd window will appear on the screen.
