Solution 1: Address the issue of a full System Reserved Partition

Launch Partition Master, enter the Partition Manager, select the hard disk/partition whose size you want to adjust, right click and choose “Resize/Move Partition”.
Step 2: Resize or move the partition
4. To shrink the partition, simply drag one of the endpoints into the unallocated space to free up room. When you're done, click OK.
2. To extend a partition, you must have unallocated space next to it (if not, create some by following the steps above). Drag the mouse over the unallocated space. Click “OK.”
