Convert system disk from MBR to GPT safely
Windows 7, announcing to make your PC simpler and things you do every day easier, has come to us now. True, many Windows fans have rushed to use and test it before it releases officially and give thumb up to its good performance and advanced features. However, there is still some different voice: "Windows 7 won't let me expand partition; boot errors after expanding Windows 7 partition, things like that. How to expand or extend partition in Windows 7/Windows 8, say, expand the system partition if needed?"
1. Right click My Computer and choose Manage -> Storage -> Disk Management.
2. Select the adjacent disk of the disk you want to extend, right click and choose Shrink Volume to create some free disk space.
3. Select the disk you want to extend, right click and choose Extend Volume to expand the partition.
While please note that there must be unallocated space behind the partition which you are going to expand if you want to expand partition with Windows built-in Disk Management utility. Otherwise, you might find that the Extend Volume option is greyed out and not available. At this moment, you have two choices to solve this problem: delete a partition or expand partition with third-party partition manager software.
When Disk Management in Windows 7 cannot manage your partition as you desire or you know little about Windows, an easier and safer alternative solution, EaseUS free partition software will be a nice choice to expand partitions in Windows 7. Here is the step-by-step guide.
Step 1. Download and launch EaseUS free partition tool. Right click the D: drive and choose "Resize/Move partition" to carve up free space for the system partition(C: drive).
Step 2. Position the mouse pointer on the partition that you need resize and drag the handle to adjust its exact size.
Tips: Sometime the unallocated space is on the left of the partition you want to extend, just drag the left partition handle leftwards to the size you want.
Step 3. Click "Apply". You can successfully expand partition and get a bigger C: drive.
EaseUS Partition Master, comprehensive hard disk partition tool and system optimization software for Windows-based administration, not only enables you to expand or extend Windows 7/Windows 8 partitions without data loss, including extending system partition without reboot.
