"Why Is Delete Volume Greyed Out?"

If you're encountering a "Delete Volume Greyed Out" issue on your Windows computer, you might be puzzled as to why this occurs. Even after deleting all files within the partition, the issue persists, and the disk still appears occupied.

Well, here are the most common reasons that cause these errors:

    1. Operating System files: The Delete Volume option will be disabled if the partition you're trying to delete contains the operating system files.
    2. Page file: Page files store the data currently in the RAM, and these hidden files are saved on a specific volume of the hard disk. If there's a page file present in the RAM, you won't have the Delete Partition option available when attempting to delete that volume.
    3. Virtual memory files: It's possible that virtual memory files are configured on the partition, which is why the Delete Volume option is grayed out.
    4. Second partition on the USB drive: If the USB drive has a second partition, it cannot be deleted, and the Delete Volume options will be disabled. To fix the issue, you'll need to remove the second partition from the drive.

Now that you're acquainted with the root causes, let's explore the solutions to address it.

Warning
You need to be cautious when deleting system partitions. If you erase the operating system, it will result in the system being unable to boot. Therefore, make sure to back up all crucial data before proceeding with partition deletion.

How to Resolve the Grayed Out "Delete Volume" Option

Method 1: Delete Partition Including System using Partition Master Tool

If you wish to delete the system partition, you'll need to create a Windows boot disk and then proceed to delete the system partition or C drive within WinPE. Thankfully, you can utilize a third-party utility - tools Partition Master for an all-in-one solution. This is a secure and user-friendly software that provides an excellent feature for deleting partitions, including the system partition.

There are two steps involved in deleting the system partition. Don't worry, we'll provide a detailed guide that even beginners can easily follow. Here are the steps:

Guide 1: Create a Bootable Drive

Step 2. Launch AOMEI Partition Assistant, and locate the "Bootable Media" feature on the left side. Click on it.

Step 3. When the drive is available, you can select USB or CD/DVD. However, if you don't have a storage device on hand, you can also save the ISO file to a local drive and then burn it to a storage medium later. Once you've made your choice, click the "Create" button to start the process.

    Check the Warning message and click "Yes".

Step 4. When the process is complete, a pop-up window will appear, asking if you want to restart your computer from the bootable USB.

Method 3: Remove the Virtual Memory Partition

Virtual memory stores system files with the .SYS extension in the C-drive. These files, also referred to as pagefiles, serve to save data from applications and ongoing processes by storing information from the RAM. To decrease the Input/Output (I/O) load on the drive, you need to remove these files from the virtual memory partition. Here's how to do it: 1. Press the Windows key + R on your keyboard to open the Run dialog box. 2. Type "sysdm.cpl" in the dialog box and press Enter to open the System Properties. 3. In the System Properties window, click on the "Advanced" tab. 4. Under the "Advanced" tab, click on the "Settings" button located under the "Performance" section. 5. In the "Performance Options" window, click on the "Advanced" tab again. 6. Under the "Virtual Memory" section, click on the "Change" button. 7. In the "Virtual Memory" dialog box, you'll see the current partitions and their settings. Uncheck the "Automatically manage paging file size for all drives" option. 8. Select the drive where your virtual memory is currently stored (usually the C: drive) and choose "No paging file" from the drop-down menu. 9. Click "Set" to apply the changes. 10. A warning message may appear, informing you about the risks of disabling the pagefile. If you're sure you want to proceed, click "Yes." 11. Finally, click "OK" to close all windows and apply the changes. After following these steps, the virtual memory partition will be removed, potentially reducing the I/O load on your drive. However, it's important to note that disabling virtual memory could impact system stability, especially if your RAM is insufficient. It's recommended to have a sufficient amount of RAM and only disable the pagefile if you have specific performance requirements or guidance from an expert.

Step 1: Go to the search box and type "advanced system settings". Click on it to launch.

Step 2: Choose the "View advanced system settings" option.
