What Causes This Error?
This issue typically appears when:
The Windows installation files are corrupted or incomplete
There’s a problem with the USB drive or ISO image
The hard drive or partition table has conflicting data
The system doesn’t meet basic hardware requirements
How to Fix It
1. Recreate the Bootable USB (Recommended First Step)
This solves 80% of cases.
Download the Media Creation Tool from Microsoft:
https://www.microsoft.com/software-download/windows10
(or Windows 11 link for newer systems)Use it to create a fresh USB installer (at least 8 GB in size)
Plug it directly into a USB 2.0 port (not 3.0) for better compatibility
2. Remove All Other USB Devices
Disconnect printers, external drives, or dongles that might confuse the installer.
3. Delete All Partitions During Setup
When you get to the drive selection screen:
Click “Custom: Install Windows only (advanced)”
Delete all visible partitions (make sure you’ve backed up your files!)
Select the unallocated space and click Next
Let Windows create the partitions it needs from scratch.
4. Run a Memory Test (Optional)
Faulty RAM can also cause this error:
Press
Windows + R, typemdsched.exe, and run the Windows Memory Diagnostic
