'Non-system disk or disk error' in Windows – How to kick it out

Its all about the self explanatory features Windows which have made it this popular. But , at the same time, its more prone to viruses and malware. Regardless of the reason, if any Windows error leads to an inaccessible data then restoration of the data from the backup is the foremost choice. If back-up is not up to date or failed to restore the data, then Windows data recovery software is the only choice you are left with.

One example could clear the concept here. Suppose one fine day , you started your computer and got a dark screen with an error message flashing on the screen. The system did not boot further making your data in the hard drive unavailable. The error message that had flashed on the screen is as follows:

“Non-system disk or disk error”

Cause:

There can be more than one possible reasons behind the above problem. Before listing the same, a simple analysis says that may be your start-up device does not contain any boot file and Windows is trying to load that device. Other possible reasons can be any of the following:

• The parameters set by the CMOS drive settings may be incorrect for the device from which the system is trying to boot.
• A troubled hard disk drive.
• Virus attack or malware intrusion.

Solution:

In order to resolve the above issue, follow the steps individually and try to boot the system thereafter.
• Try removing any non-system disk attached to the system that is any non-bootable system disk that has been at the point, from where the system is tend to boot, including the CD/DVD drive, floppy drive etc.
• Try to check, whether the boot sequence of your system is correct or not that is the boot device selected should contain the boot files or the operating system files installed in it. Go to the settings at the startup and set the correct boot device accordingly.
• If your system contains multiple hard disk drives, ensure that the drive from which you are trying to boot has been installed with a bootable operating system, such as Windows XP, Vista etc.

One very important point I would like to mention here is , please never compromise with the quality of anti virus program or else you may have have to pey more for it . The cost may be in terms of your valuable data also..
