Windows 10: My 3 drives merged to single drive

I updated the new software shown in settings of my windows 11 laptop. After updating I got a blue screen error. After resolving it I got further more errors in functions of my laptop. So I reset my laptop by removing all files. After restarting a couple of times and following instructions of my manufacturer's os recovery method the laptop turned on. Then I found that there's only one drive which OS:C 512gb. Previously I have 3 drives with equal partitions of 512gb. Can I split the new OS drive to three drives like before reset.

how to merge c drive and d drive

It depends on a couple things.

If you have two separate physical C and D drives, you can't merge them.

If the D drive is a partition (not a drive) and its to the right of C:\ in Disk Management, you can right click C:\ then click Extend.

Press Windows key + X

Click Disk Management

Take a screenshot then post in a reply here.

If the layout is similar to how I described it, try the following. Make sure important data is backed up if there is any.

Select the D:\ partition

Right click the ‘D:\’ in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition (C:\). Right click the System volume and click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.
