In reply to pal1's post on November 13, Same with me C: drive partition cannot be extended. The 'extend' option is always greyed out for C:. The 'extend' option is always grey-ed out for my C:. Step 1. Step 2. Right-click on the partition C: you want to increase space and select " Extend Volume " from context menu.

Note: If there is not unused space close to the C: drive usually to the right , the "Extend Volume" option will not be available. Step 3. Now the "Extend Volume Wizard" shows up and it will help you increase volume size by adding space from one or more additional disks.

Click Next button to continue. Step 4. Set the amount of space you want to add to the partition and click Next button. Disk Space is calculated in MB and you can only extend the volume to the available space shown below, because the disk cannot be converted to dynamic or the volume being extended is a boot or system volume. Step 5. Click Finish button to complete the wizard.

Then you should see the C drive is extended in Disk Management console. Though Windows Disk Management is able to extend system partition without data loss, it has limitations.

There should be contiguous unallocated space next to the C system volume, otherwise, the "extend volume" will be grayed out. For example, you have C, D and unallocated free space on hard drive, and you can only add free space to D drive, as C drive is not next to free space. In this case, you may have to delete the adjacent partition of C drive in order get free disk space. Deleting partition removes all data on the partition, and you need to back up data to a different location before deletion.

Since Disk Management can add free space to adjacent partition, you may wonder what to do with unallocated space which is not next to C drive? You can either create a new partition on unallocated space or add free disk space to system volume with third-party software. For instance, there is unallocated disk space between partition F and H, and you can use DiskGenius to add it to C drive, as below: right-click on free disk space and choose "Allocate Free Space To", after which you can specify which partition to add the space.

To lift the limitation on Disk Management, you can use free third-party disk partition software DiskGenius. DiskGenius Free allows users to add unallocated space to any partition as well as move disk space between partitions.

Besides, it is also able to resize partition and split partition without losing data. Download and install DiskGenius Free Edition, and then launch it from your computer. Right-click on the C drive you want to extend in DiskGenius, and select " Extend Partition ", as follows. In the pop-up windows, click a partition from which you want to move free space. You can select a partition which contain enough free space so that you can move it to system partition.

Set disk space you want to move to C drive and click Start button. You can drag the arrow between partition bars or enter the exact disk space to be moved to C drive. Click Yes button to continue when DiskGenius lists operations to be done during the partition resizing process. Step 6. Please close all other programs and save unfinished content, and click OK button. Please do not close the program when the partition resizing is ongoing, as partition may get corrupted if you force to interrupt the process.

Changing size of partition will modify the start and end position, move data, modify parameters in MBR and DBR of related partitions. Thus, it is not risk-free even though the disk partition software is reliable and effective. If partition contains errors or operating system is not working well, or there is power failure during resizing partition, there is possibility that partition might got corrupted and data got lost.

Therefore, it is recommended to make a backup for related partitions in advance in case of any unexcepted errors. Besides, it is not advised to resize, extend, split or shrink partition when hard drive has a hardware failure such as bad sector. It is not recommended to resize partition via DiskPart commands unless you are specialized user, for it is easy to make mistake if you are not familiar with these operations and the result is data loss, partition damage, system failure, etc.

Besides extend system partition Windows 8, there are some other functions like shrink partition, delete partition and format hard disk. It doesn't allow users to operate " Move Partition " or "Resize System Partition" when there is no unallocated space right behind system C partition. It cannot shrink the volume beyond the point where the unmovable files are located, or, it can only shrink basic volumes that have no file system or use the NTFS file system. Because of such limitations, users need to search some professional partition software such as partition magic Windows 8 alternative, AOMEI partition software to resize partitions, which can help you to increase or reduce the disk space of partition without any limitation.

This competitive software has three easy-to-use wizards to simplify extend and shrink partition operations, copy partition and disk operations. Free download and see how it works. As we can see there is no unallocated space. So, we need to shrink F.

Then click "OK".
