Gmt partition error and data recovery
To isolate the issue, we’d like to get the following information:
- What is the original operating usage of your device?
- Do you still have the installer of the original operating system? If yes, you’ll be needing that to perform a clean install before you can install Windows 8.1 again.
To create a backup of your data, we call to mind transferring the hard drive to a operational PC and then try if it will be read as an external mass storage space.
