local storage problem

Windows can be installed to an SSD using local media, but the supported and documented methods use bootable external media (USB/DVD), a mounted ISO, or network-based deployment rather than third‑party boot managers.

From the available documentation, the supported approaches are:

1. Use a bootable USB or DVD created from an ISO
   • Create Windows installation media from the ISO or via the Media Creation Tool.
   • Boot the PC from the USB/DVD and run Windows Setup.
   • During setup, choose Custom and select the SSD as the target drive.
     This is the standard method described in the Windows Setup technical references and “Install Windows from a Flash Drive.”
2. Boot from USB and prepare/convert the SSD, then install
   If the SSD is new or needs repartitioning (for example, converting MBR → GPT):
   • Boot from Windows installation USB/DVD in UEFI mode.
   • In Windows Setup, press Shift+F10 to open Command Prompt and use diskpart:

          diskpart
          list disk
          select disk <disk number of SSD>
          clean
          convert gpt
          exit
     

   • Close Command Prompt, return to Windows Setup.
   • Choose Custom install, select the unallocated space on the SSD, and click Next.
     Windows Setup will create the required partitions and install to the SSD.
3. Install to SSD as a standard internal drive
   The SSD is treated like any other internal hard drive:
   • Ensure the SSD has sufficient capacity (minimum 16 GB, realistically much more).
   • Boot Windows Setup from USB/DVD/ISO.
   • Select the SSD in the Where do you want to install Windows? screen.
   • If multiple drives are present, verify the correct disk before deleting or creating partitions.
4. Advanced scenarios (VHD/VHDX boot)
   For scenarios where Windows is installed into a VHD/VHDX and then added to the boot menu:
   • Prepare the VHD/VHDX and apply a Windows image to it.
   • Use bcdboot from WinPE or an existing Windows installation to add a boot entry pointing at that Windows instance.
     This is documented for native boot to VHD, not specifically for launching Setup from a local WIM.

The documentation in context does not describe or endorse using third‑party tools (such as EasyBCD) to create a temporary boot entry that launches boot.wim directly from a local partition for installation. The supported path is to run Windows Setup as a bootable program from:

• USB key
• DVD
• Mounted ISO
• Network device

Once Windows Setup is booted by one of these supported methods, installing to an SSD is fully supported, including wiping, repartitioning, and converting the SSD to GPT if needed.
