After successfully installing a dual boot environment, adding Ubuntu 13.10 to a preinstalled Windows 8 configuration I decided to increase the unallocated SSD disk space after reading about the benefits of over-provisioning. So, using miniTools Partition Wizard in Windows, I shrunk the NTFS Windows partition somewhat. That seem to have completed successfully. However, when I boot up Linux and launch GParted, it gives the following error message at startup:
The backup GPT table is corrupt, but the primary appears OK, so that will be used.
Everything seems fine and dandy with the system, but I am worried that I will have a problem should the main GPT table become corrupt for some reason.
I have used gdisk to backup the GPT table to a file, but is there a way to create a new backup GPT table?
