If you get the error “invalid Partition Table!” when trying to boot a laptop or PC try the following process.
Please do this as your own risk as
- Disconnect or remove all removable or external drives.
- Restart the computer.
- Wait for the BIOS status screen to appear. The screen will either have the logo of the computer manufacturer (such as Dell) or be black with white letters and many technical details.
- Press and hold the “F8” key as soon as the BIOS screen disappears. The Windows “Advanced Boot Options” menu appears on the screen.
- Select “Repair Your Computer,” and then wait for the Windows 7 Recovery Environment to load.
- Select your keyboard layout from the drop-down box.
- Log in using an administrator account, if necessary. The “System Recovery Options” window appears.
- Click “Command Prompt.”
- Type “bootrec /fixmbr” without quotation marks.
- Wait for the process to say successful.
- Type “bootrec /fixboot” without quotation marks at the command prompt.
- Wait for the process to finish and restart the computer to see if it worked. If it did not work, repeat steps 2 through 8, then continue to the next step.
- Type “bootrec / RebuildBcd” without quotation marks at the command prompt. If this is not successful, it could be the disk is not recoverable and you will have to format the disk and reinstall the operating system.
Should you encounter any failures during this process you may need to reinstall the Operating System or have a faulty drive. Consult a technician if you are not able to recover Windows.
