This error typically occurs when you are trying to create Installation Media using Microsoft's MediaCreationTool. Try formatting your Flash Drive using diskpart. This will definitely solve your problem.
- Press CTRL + R > Type "diskpart" (without quotes) > Click "Yes" on the Permission Screen.
- Enter the following command:
list disk
2.1. When a list appears with your disks installed on the computer, identify the Disk (Flash Drive) you want to format > See the Disk Number (First column).
2.2 Run the following command, replacing the letter "X" with the Disk Number you want to format.
select disk X
2.3 Run the next command to completely wipe the Disk.
clean
- Close the terminal > Press the CTRL + R shortcut > Type "diskmgmt.msc" (without quotes) to open Disk Manager.
- Identify the formatted Disk or Flash Drive (contains a black stripe indicating that the Disk has an unallocated region) > Right-Click the Mouse on the black striped area > Select "New Simple Volume" > Proceed through all steps > At the end, select "Finish".
- Wait for completion > Done! Now try creating the Installation Media again.
