Install Windows 10 onto re-formatted harddrive

    Question

  • I realize this is a Windows 8.1 forum, but couldn't find anywhere else to post.  I've got 64 bit Toshiba that came pre-loaded with 8.1 that I upgraded to Windows 10.  I have since cleaned hard drive using DISKPART.

    Here's what I have now....

    USB stick with  downloaded - Win10_1511_English_x64.iso (unzipped)

    Disk 0 - Online 465 GB  0 (free) GPT

    Disk 1 - Online 14 GB    0 (free) (not GPT)

    Volume 1 -  C   J_CCSA_X64F (Label)  NTFS   Partition   465 GB  Healthy

    Disk 0 Partition 1 465 GB 1024 KB (Offset)

    When I try to run install from USB stick, I get the following error... "We couldn't create a new partition or locate an existing one.  For more information, see the Setup log files."  

    ....And I can't find the Setup log files.

    I converted Disk 0 from Mbr to GPT to resolve file type error.

    I appreciate any suggestions.  Thanks, Don

  • Hi,

    Do you create relevant partition for GPT disk?

    If not, please try below steps to create:
    1. Use USB to boot and see the Install Windows screen, press "Shift+F10" and open CMD.
    2. Type Diskpart, press Enter
    3. Type List Disk , press Enter
    4. Type Select Disk # (where # is the number your drive shows up as), press Enter
    5. Type Clean, press Enter
    6. Type Convert GPT, press Enter.
    7. Run create partition efi size=xxx (default value for Windows is 100MB, for Mac is 200MB, we can appropriately increase, for example 512MB), then run format quick fs=fat32 label="System"
    8. Run create partition msr size=xxx (it's a recovery partition, default value is 128MB, we can increase to 512MB)
    9. Run create partition primary size=xxx (it's system install partition, i.e. C), then run format quick fs=ntfs label="Windows"
    10. Restart computer then select UEFI device to boot and install Windows.

  • Boot your USB key in UEFI mode to install to GPT disk. If still a problem, since the disk is blank anyways, use Setup to delete the partitions and install again.

  • Your best bet is to just clean the disk with diskpart and re-run the USB stick, letting setup partition the drive. Your post shows the disk is not clean. My guess is that since your post shows only one partition, you don’t have a system partition or UEFI reserved partition.
