Windows 10: Extending C drive which placed in disk no 1 and E placed in disk no 0

I have in my disk manager about 490 unallocated GB in disk 0. My C drive is in another drive named "disk 1"- because of it I cant move the unallocated GB to my C drive. There is 1 quastion I found in google about this specific problem it has 1 comment that says to copy all my c drive data to a new drive that I will create in my disk 0. I'm afarid that If I will do this my computer won't find the important files that have been in c drive and My pc will not be able to open up itself or important programs. I really need that GB to my c drive- it has only 2 free GB. ps. before i undest

Cannot merge C drive (disk 0) with unallocated space (on disk 1)

Hi all,

I need some advice on whether it is possible - and if yes, how to merge my C drive on disk 0 with D drive on disk 1.

The problem is: my C drive is getting full soon, but previously after I deleted D drive and make it unallocated space (the bar of current D drive will change to black from blue), I still cannot expand C drive by adding the 100GB unallocated space into it.
If I right click on C drive, the "expand" item is in gray.

I've searched online for solutions but so far only have seen same questions around. Does any one know the solution and do a big favor to explain how to do it step by step? Thanks much in advance!

P.S, sorry that the interface is not in English. Below page shows the "Disk Management" function, and you can see that:

1) Disk 0 has 55.78G, including C drive (55.21GB), 100MB of something I don't know what it is, and 473MB of recovery zone

2) Disk 1 has 100GB D drive, and 831.51GB E drive

 

switch disk numbers: I want Disk 0 to be Disk 1 and Disk 1 to be Disk 0

Hi, My computer contained a normal HDD hard drive. I recently upgraded to a SSD. The original HDD is Disk 0 and the new SSD is Disk 1. The windows OS is on Disk 1. I want to dual boot my system with Windows and Ubuntu with both OS being on the SSD. Since
the SSD is Disk 1 the Ubuntu install goes directly to Disk 0 because Disk 0 is first on the list. How can I switch the two Disks so my SSD drive is Disk 0? Thanks.

 

Windows 10 Disk Management - cannot extend C: drive to allocated space

Hello, I followed all of the steps listed and it is still not working. The issue may be that the unallocated space is located on Disk 1 when my C: drive is on Disk 0 and I cannot seem to get them both on the same disk. Do you know if there is a solution
for this?
