Windows 10: is it ok to delete the the C: drive and move to D: drive as the main one?

im not the best at these kinda stuff. i dual booted 2 windows 10 operating systems. the C: drive contains a 32-bit Windows 10 version, and the D: drive contains a 64-bit Windows version. ive been using the 64-bit version a lot now and its been a while since i use the 32-bit version. i wanted to delete the whole 32-bit os from the C: drive and merge the unalocated partition with the D: drive. is this method safe? and if it isnt, can anyone suggest me other methods? im too dumb for this.

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.

 

C: and D: drives

I was able to free up the D drive by deleting the Windows 8 from the D drive and creating a restore point on the C drive. The D drive is now free. Thank you for the quick reply.

 

I deleted D drive in order to extend c drive but c drive will not extend

So I have 237gb of storage on my C drive and it is nearly full, my D drive has 931gb of storage and is completely empty. in an attempt to solve this problem I went online looking at different forums and articles and many recommended that I delete D drive
so i can extend C drive, but it will not give me the option after deleting it.
