from other drive. Thus, the built-in Disk Management tool is your choice to help
extend system volume. In Disk Management, right-click C drive and click “Extend
Volume” and you are able to enlarge system drive. However, if the unallocated space

options is greyed out. What would you do now? Would you like to backup all data and
format the hard drive, and then reinstall the operating system to reallocate it? Or,
would you like to backup in-between partitions, delete them to extend system volume?
