I had accidentally converted my primary Windows C drive to a basic disk, instead of the default one.
So, currently I have 488.28GB of unallocated space on my system. P.S: I had put a new SSD of 1TB storage to my laptop a few days ago. I had created 2 partitions of 500GB each, where "C" was where my windows 11 OS resides, and the other one was created manually.
Now, when I try to create a simple volume from this unallocated space, I get the following errors-
I am unable to figure out a method to resolve this error.
It would be very helpful if anyone could help me fix this error.
Will reformatting my laptop, help me fix the issue?

I have the same as yours, main issue that your disk is GPT. you need convert to MBR and format it.
1, Run command prompt as Admin (same step previous)
I'm sorry to hear that.
Search CMD in the taskbar search and right click Command Prompt and run as an administrator.
Type “diskpart” and press Enter.
Type “list disk” and press Enter.
Type “select disk X” (where X is the number of the disk you want to create the partition on) and press Enter.
Type “create partition primary size=X” (where X is the size of the partition you want to create) and press Enter.
Type “format fs=ntfs quick” and press Enter.Keep me posted. Thank you.
The following error came, when I entered the command - "create partition primary size=X" --
No usable free extent could be found. It may be that there is insufficient
free space to create a partition at the specified size and offset. Specify
different size and offset values or don't specify either to create the
maximum sized partition. It may be that the disk is partitioned using the MBR disk
partitioning format and the disk contains either 4 primary partitions, (no
more partitions may be created), or 3 primary partitions and one extended
partition, (only logical drives may be created).

Hello! My name is Mostafa; I will assist you today.
I’m sorry that you are experiencing this issue.
Could you please change the amount from 500000 to 450000 to see if the issue persists?
Have you tried to use 3rd party app to see if you get the same error such as a mini tool partition wizard?
Let me know the result. Thank you.
Hi, I tried doing that, but the issue still persists. I tried using the Mini tool partition wizard. But it didn't work. I tried other apps to possibly defragment the C drive and do something, but it did not work.
