  2. Partition problem during clean install of Win 10

    Partition problem during clean install. I get the message "We couldn't create a new partition or locate an existing one. For more information, see the Setup log files."

    I'm trying to do a clean install (after a successful upgrade so this laptop has been activated on Windows 10). Super basic situation - single blank internal SATA HDD in a 2010-era Dell laptop, installing from a USB stick, same installation media used for the
    successful upgrade. No complications - dual boot, multiple drives, Linux, etc.

    After I select the Custom install option the window showing disk partitions is shown. My disk is there (the only one) but no matter how I delete/create/format it I get the message noted above.

    I have searched the web of course, found and tried the following:

    • Made sure the hard drive is first in the boot order in the BIOS
    • Used the "diskpart" utility and the sequence of commands suggested to clean, partition and format the disk.
    • Tried leaving the disk blank (without any partitions) and also tried creating a single Primary partition.
    • Pulled the USB stick for a few seconds right after accepting the license, before the custom install selection. (A weird suggestion but I tried it).
    Any ideas?

    Saving free space on SSD (Regarding multiple obligatory partitions on main drive)

    Gerry Here just copy-paste some irrelevant response.

    Well, **I've figured it out**. Here my solution (I Take no responsibility from any damage that might arise from this process, and I do not guarantee it to work for u.)

    We'll assume u have 2 disks; SSD and HDD.

    Also NOTE: I Work in a GPT-Disk partitioning scheme, I don't know if it's applicable on dos-style MBR partitioning.

    General-methodology wich we are going to work with (or TL;DR).

    • Delete all partitions on all drive
    • Install Windows on the HDD Drive
    • Install Windows on the SSD Drive (yes, twice!)
    • Repartition the HDD to free up and reallocate as we wish (The only parition that HAVE to be there is the EUFI System (Fat) )
    • After freeing up HDD space, move user folder to the HDD
    • PROFIT
    And in more detail:

    THIS GUIDE ASSUME THIS IS A FRESH PC - THAT U DO NOT HAVE ANYTHING U NEED ON EITHER DISKS.

    * - Asterisk, not a real step, just additional information

    • Boot into windows 10 installation
    • Clear ALL partitions on BOTH drives
    • Let windows install itself onto the HDD, We'll call this installation win-hdd
      • There is no need to actually boot into this OS.
    • Boot into windows 10 installation
    • Let windows install itself onto the SSD. We'll call this installation win-ssd
      • *What would happen now, Is that windows detects the recovery and eufi partitions and does not need to create such additional partitions on your ssd. It would only create a 16MB windows reserved partition.
      • *Your boot partition would be hdd/eufi; But since windows detect it's own bootloader it would allow you to duel-boot between win-hdd and win-ssd(default)
    • Optional: During windows-ssd first run wizard switch to audit mode (CTRL+SHIFT+F3)
      • *We would use audit mode to:
        • * Optional1: Repartition hdd
        • * Optional2: Change "Users" folder to the hdd.
        • * If u do not want to move Users folder, u can do 6.2 After win-ssd fully boots instead
      • Repartition hdd & move Users folder:
        • Using a 3rd party tool such as "MiniTool Partition Wizard" you can do the fallowing *as you wish*:
          • Delete win-hdd partition
          • Delete recovery-hdd partition
          • Delete windows reserved (16 mb) partition.
          • You can also later move the EUFI to the start of the hdd disk, if needed
          • Create new partition (free to use) on hdd.
          • Make sure to properly assign drive letters to all drive as u wish
          • Fallow
            this guide
            to relocate the User folder (Starting from Step 2)
    • Boot into windows-ssd; If u do not know which one (int the OS selection screen) It's safe to assume that the automatically-selected one is the win-ssd.
    • If u have not performed 6.2 Yet, this is the time to do that now.
    GLHF.

  10. Beware - clean install with multiple HDD's and UEFI take care !!!

    in Windows 10 Installation and Upgrade
    Beware - clean install with multiple HDD's and UEFI take care !!!: With some systems, individual drives could be disabled in BIOS. Yep this is a simple solution, and it works. I disabled my M.2 W7 drive on my X299 when I installed W10 on the 860 Pro, the installer never even saw it. But as you said Jim, IF it`s possible.
