Most computer users, I believe, are not likely to perform operations on system partition, because system partition stores boot files of the operating system. Once these important files are damaged by inappropriate operations, the OS may get corrupt and even leading to serious data loss, which I believe is a situation that nobody wants to encounter.
However, we have to resize system partition sometimes, such as to cope with low disk space issue, or to shrink system partition size as it is taking too much disk space. Today what I am going to talk about is how to extend Windows 7 system partition, to help users who are unable to increase C drive in Windows 7 using Disk Management.
Extend C Drive Windows 7 Greyed out
Users who are familiar with Windows built-in Disk Management tool know that Disk Management enables them to resize partition since Windows 7, and the corresponding features are Extend Volume and Shrink Volume.
To access Disk Management, we should follow these steps:
Right-click My Computer -> press Management -> press Disk Management.
OR press Win + R keys -> input diskmgmt.msc -> click OK or hit Enter key.
Then we can right-click on a partition and the new features will appear. (image attached)
The above picture shows that extend Windows 7 system partition is possible by using this Disk Management tool. In this case, we just follow the prompt and extend C drive in Windows 7. But most of the time we may find Extend Volume is greyed out as showing below.
Well, in one of the following situations, Extend Volume will grey out:
- There is no unallocated space following the target primary partition.
- There is no free space following the target logical partition.
- The target partition is not in RAW or NTFS file system.
If no unallocated space are available to use, I think users will have to delete a primary partition that immediately follows the system partition to increase C drive in Windows 7. And data backup should be given priority.
