[Instead of the below, just use the align partitions option in the bootable Mini Tool Partition Wizard. It's just so much easier]
Lastly, determine if the total allocated space at the end of the drive represents 10% of the drive space. If it does not, resize the VERY LAST partition (expand or shrink, as necessary) so that 10% of the drive space is left unallocated at the end. (If you have a Samsung drive, you can do this last step in Windows using the Samsung Magician software, through which you also optimize the OS and enable RAPID mode.)
If Windows does not boot after these procedures, check out GParted FAQs 14, 15, and 16 for how to use the Windows install disc to repair boot options.
