Problem encountered during startup or installation following a new motherboard upgrade.
Problem encountered during startup or installation following a new motherboard upgrade.
During the rebuild, I modified the motherboard but left all other parts intact. Now the original Windows setup isn’t recognized, and installing it with the Media Creation Tool isn’t working. I thought changing just the motherboard would let me resume from where I stopped, but the OS didn’t appear. Here’s what I’ve tried so far:
- Gigabyte X570 I Aorus Pro Wifi (BIOS F11)
- Ryzen 1700X (X570 BIOS may support 1000-Ryzen versions)
- Corsair 2x16GB RAM, Samsung 970 EVO Plus NVME
- BIOS reset to default settings
- Device Self Test passed in BIOS
- All hardware detected in BIOS
- Windows Support enabled
- PXE Boot option turned off
- ROM set to Disabled
- Storage Boot Option turned off
- UEFI only selected
When I boot into the boot drive, it detects hardware but fails to load the OS. In the Windows PE environment, I see a Windows installation folder but after restarting, the setup halts and shows “No operating system found.”
If I try to boot into “UEFI: Storage Device 1532, Partition 1” (Windows Creation Tool), I can install Windows, but during the restart the process stops abruptly. In the Advanced Options menu, I can choose to continue with Windows 10, yet it restarts without OS installation.
I’ve deleted the “Windows.old.000” folder because it was empty, but my original installation files are now in a different location. I moved everything from Windows.Old into D: and copied relevant folders into a “WinOS” folder inside D:.
Using CMD commands during boot, I can move files between directories like:
- WinOS → Program Files
- WinOS → Program Files (x86)
- WinOS → ProgramData
- WinOS → Users
- Windows.old → Windows
Despite these steps, I’m stuck with multiple partitions and corrupted files. The data on the boot drive is critical, and I’m unsure how to safely reinstall without losing it. Any advice would be greatly appreciated.
You're absolutely right, but it seems like a common misunderstanding. Swapping the MOBI or CPU usually means a full Windows reinstall. Even if it works, system stability would likely suffer because of incompatible chipset drivers. Move that drive to another PC as just storage, remove the unnecessary part, and reinstall Windows there.
Do you possess an additional storage device within this setup? The primary boot location remains C: When you lack access to another machine, the most straightforward approach (though involving multiple steps) is to acquire an affordable SSD, remove the existing NVMe unit, perform a fresh Windows installation using the SSD, reinstall the NVMe drive afterward, and ensure the system boots from it. Once transferred, you may reinstall the NVMe drive, format it, detach the SSD, and reinstall Windows. For future use, it's advisable to keep a dedicated drive solely for data storage!
Learned to resolve the issue independently without reinstalling or creating backups: Using the Windows Media Creation Tool on a USB stick, open Command Prompt in WinPE: Troubleshoot → Advanced options → Command Prompt. Enter commands like “bcdboot D:\Windows /S D:" (swap D: with your installation drive) and “diskpart list disk select disk 0” (replace 0 with your boot volume). After selecting the correct volume and running the steps, a restart allowed me to boot into the original install without issues. A guide on MBR and GPT drives was helpful. In my situation, I needed to rename a secondary drive letter so all folders and programs functioned properly.
