Hi everyone,

​I’m seeking help with a Windows installation that keeps failing. I am getting the following error message during the "Installing Windows" phase:

​Error Message: "Windows cannot install required files. Make sure all files required for installation are available, and restart the installation."

​Error Code: 0x800701B1

​

The error usually pops up shortly after the file expansion starts. I have tried restarting the installation multiple times, but it fails at the same spot.

​Hardware/Setup Details:

​Installation Method: USB Flash Drive.

​Drive being installed to: SSD M2

​PC/Laptop Model: [Insert your model here, e.g., Elite notebook  840 G3

​Has anyone encountered this specific code (0x800701B1) before? I've read it might be a USB connection issue or a drive failure, but I’m not sure which direction to take first. Any advice on how to troubleshoot this would be greatly appreciated!
