    Windows 10 installation error we couldn't create a new partition or locate an existing one


    Hi AllI have to install Win10 again as I am unable to update it due to unsolvable errors. My HDD is 1TB with 2 partitions one had Win10 on it which I have removed and the other partition has my stuff over 200gb which I cant back up. When I try to install Win10 on the original partition after deleting all the system reserved partions and Win10 partition and creating new partition using un-allocated space. I get this error "We couldn't create a new partition or locate an existing one." I looked up some fixes but they will clean up whole hard disk using diskpart. Is there any possibility of

  3. "We couldn`t create a new partition or locate an existing one."

    Try this:

    Before you get to that message, press SHIFT + F10 to open a command prompt.

    Run diskpart.
    At the diskpart prompt, run these commands:

    list disk

    At this point you should see the SSD as disk 0. If it has another disk number, use that number rather than "0" in the next command.

    select disk 0
    clean
    exit (to exit from diskpart)
    exit (to exit from the command prompt)

    That should clear the contents of the disk. The entire disk space should then show up in Windows setup as "Unallocated Space" as in the screenshot below.
