during the start up I get an MBR3 Error.

I purchased the computer 6 years ago as a prebuilt with Windows 7 home premium already installed but since then I have moved several times and my install disk as well as my product key have gone missing.

What to do?

Windows for home | Previous Windows versions | Windows update

Hi Tristan,

The issue you are experiencing may have been caused by a corruption in the boot sector or due to a software conflict.

To help resolve your concern, you can repair the boot sector by running these sets of commands using Command Prompt:

  1. On Start menu, type Command Prompt, right-click the result and then choose Run as administrator.
  2. Type or copy each command followed by hitting Enter:

bootrec /fixMBR

bootrec /fixBoot

bootrec /rebuildBCD

Let us know how it goes and we'll assist you further if needed.
