First Partition Too Close to the Beginning of the Disk, How to Fix

I am running the MBR2GPT utility, but it came up with an error: the first partition is too close to the beginning of the disk. It requires me to move 17 KB further back. However, the first partition is unshrinkable, and it's the one giving me errors. How can I fix this?
