The following information on this error has been compiled by NeoSmart Technologies, based on the information gathered and reported by our global network of engineers, developers, and technicians or partner organizations.
When a computer is turned on, the BIOS picks an eligible, bootable hard drive and then calls code stored in the MBR at the start of that hard drive. That MBR code in turn loads the bootsector from the active partition. Then, the bootsector code loads the bootloader, which is responsible for loading the operating system. One of the most common causes of this error is the boot-related files that became either missing, corrupt, or misconfigured. That could happen because of disk write errors, power outages, boot sector viruses, or errors made while configuring these files manually.
Another possible reason for this error is a boot sector virus that prevents the computer from loading. In that case, running an antivirus program that is capable of deleting boot-sector viruses may solve the issue. This error may also occur after the key parts of system registry became corrupt. The special EFI bootloader introduced in Windows 8 may also become corrupt or misconfigured.

If it's not, set the value to 0. If any of these keys don't exist, you can try to replace the current registry hive by using the hive from RegBack. To do this, run the following commands:. Check whether there are any non-Microsoft upper and lower filter drivers on the computer and that they don't exist on another, similar working computer.
If they do exist, remove the upper and lower filter drivers:. These filters are mainly related to storage. You might find these filter drivers in some of the following registry entries. These entries are under ControlSet and are designated as Default :. Then defrag the file to make sure it can be used by Grub4dos. If you disable this option, drivers will not be installed. This option will be remembered for future uses. Leave a Reply Cancel reply Your email address will not be published.
