# 3. Delete All Partitions on the Drive and Initialize It to GPT
If some other people reported that the “Virtual Disk Service error the disk contains a pagefile volume” error gets fixed finally by wiping the hard disk and initializing to GPT. But bear in mind that this operation will delete all data on the disk. So, make sure you have a full backup of your computer in advance.
Here’s how to do that using Disk Management.
Step 1. Press Win + X to open the Windows context menu and select Disk Management.
Step 2. Right-click the partition on the disk and select Delete Volume > Yes. Then repeat the same procedure to delete all partitions on the disk.
Step 3. Once wiped, right-click the disk and select Initialise Disk.
