FAQs
What is difference between GPT and MBR?
Master Boot Record (MBR) disks use the standard BIOS partition table. GUID partition table (GPT) disks use the Unified Extensible Firmware Interface (UEFI). One of the benefits of GPT disks is that you can create more than four partitions on each disk. GPT has a disk capacity that is larger than 2 terabytes.
How do I add unallocated space to my C drive?
Run diskmgmt.msc to open the disk management. Right-click on the C drive, and select the Extend Volume option to extend the C drive with the unallocated space.
