    Setup: Could not create new partition


    Hello everyone,

    Just tried to reinstall my windows. Everything works fine untill I select the drive on which the os should be installed. The error "could not create new partition" pops up. Already searched for it on the internet and pretty much the same solution comes up on every site --> diskpart, clean, assign etc... That solution doesn't work. Already tried setting it to unallocated space, system and primary, but none of those have any effect. Also, there are no other partitions on that 128gb SSD. Only 1 other HD from 750gb is installed, but that one has no partitions either.

    Anyone has another idea what might go wrong, or a possible work-around?

    Btw, I'm 100% sure the USB-stick with the installation is functioning, because my current os was installed from the same usb about 6 months ago.

    Remove the connector from the 750GB hard drive so it is disconnected (power or data, doesn't matter). Boot computer from Windows 10 installation USB flash drive, when you get to the point that shows the drives and partitions, you should see only the SSD. Press Shift+F10 to open a command prompt. Run:

    Diskpart
    Select Disk 0 (the SSD should be disk 0, if it is not, you can run list disk to see a list of drives and then select disk <disk number> for the SSD)
    Clean - this will erase all the partition information off the SSD
    Convert GPT - sets up the SSD for an install of Windows 10 compatible with UEFI
    Exit - Exit Diskpart
    Exit - Exit command prompt window

    Back at the drive and partitions list in Windows 10 setup, click the refresh button, select the unallocated space on the SSD, click Next to install Windows 10 to it. After Windows 10 is installed on the SSD, then you can reconnect the 750GB HDD.

    This is all assuming your Windows 10 installation USB flash drive is actually good. If you created it with Rufus, that might be the problem as well. After you get a good, clean install of Windows 10 on the SSD, we highly recommend you create an image of the SSD using Macrium Reflect Free and create a Macrium Reflect Free rescue drive.

    With a little bit of creativity, you can create a bootable partition on your 750GB HDD to hold both Windows setup and a rescue image. That's what I have on my dual drive laptop and desktop computers. The primary drives are SSD's, the backup drives are 1TB HDDs, to reinstall Windows all I have to do is select the HDD from the override boot menu in UEFI and it boots into Kyhi's recovery tools. From there I can either run a Windows setup or I can restore a backup image made with Macrium Reflect - either one can be accomplished and finished in about 10 minutes and it is especially important for the laptop because I can do a restore on the road with no external devices required.

    Thanks for the reply. Did not try that yet, so I will try after dinner. On a different note, do you happen to have a link on how to create the bootable partition? Sounds like a great idea. And yes, I did use Rufus but if Macrium Reflect works better, I could use that one in the future.

    Damn, just tried, and I still have the same problem. Currently working on my laptop, on which I had the same issue. Installed a fresh Ubuntu and that went without any problems. Really strange, makes me think it's the USB, but I've used the same stick like half a year ago.

    I advised another poster last week who also was having problems reinstalling, simply to use Reset. He reported back that it had been a bit slow but that it had been completely successful. I've used Reset myself a few times on different computers without problems. It gives you a clean Win 10 install but I do recommend imaging the system before you start, just in case.

    Unfortunately that is not an option anymore, considering the SSD was already formatted.

    Is the stick you are using a USB 2 or 3? If it is USB 3 then try using a USB 2. This might be what is causing the problem. See: Solved error - Windows 10 Forums

    Anyone still has an idea? Couldn't be due to some bios setting I assume, considering the USB is detected. Really annoying because I don't have another version of Windows laying around...

    It is USB 3, but if that would be the case, why could I install it last time. Besides, it does start the setup, while I think if that would be the case it wouldn't start the setup.

    On a sidenote, the setup does not detect the USB when plugged into a USB 3 port, only when I use a USB 2 port

    please read the thread that I posted, I believe it will explain why it think you need to use a USB 2 stick.
