  2. Win7 install, setup was unable to create a new sys partiton...

    Full error: Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information.

    My drive setup is as follows:

    Drive 0 200gb, trying to install win 7 on this one. This was installed into the computer recently.

    Drive 1 Total 250GB. Has ubuntu installed
    Partition 1 Primary: 140gb, ext3
    Partition 2 Logical, 91gb ext3
    Partition 3 logical 3.9GB, swap

    Both drives are sata, Drive 0 is first to boot from i believe. Anyway, i had an 80gb drive originally that failed, when i removed that I rebuilt grub on ubuntu to just recognize ubuntu and its own drive (drive 1). Thereafter I stuck Drive 0 in, and tried to install Win7 on it, and got the above error. I disconnected my ubuntu drive, and the error is still present. Heading home from work now, but pile on the suggestions. Ill try them tomorrow.

  3. We couldn't create a new partition or locate an existing one.

    So I was doing a clean install of windows 10 using a USB and I deleted all the partitions including the system reserve one. The only drive left now is "Drive 0 Partition 1". It is set as primary.

    The problem is everything I click to continue the installation, I get the error "We couldn't create a new partition or locate an existing one."

    I followed instructions from sites such as this, Error: 'We couldn't create a new partition or locate an existing one. For more information, see the Setup log files.' when you try to install Windows 8 (CP)
    and I still got the same error.

    I would greatly appreciate it if anyone could help.

    W7 Hard drive partition issue

    to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

    - press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
    - diskpart <-- start the windows command line partition management tool
    - list disk <--- list the installed hdds in this computer for the next step
    - select disk 0 <- might have to replace 0 with the number of the correct disk
    - clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
    - create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
    - exit, exit to exit diskpart and the command prompt
    - click refresh in partition manager and select your newly created partition and install to that
