The best way to create Windows 10 bootable USB from ISO image?

You'll need a stable internet connection, especially if you're using the Media Creation Tool to make Windows 10 bootable USB, since it downloads most of the installation files for you. And always pay attention to the on-screen instructions. It's a classic mistake, but sometimes folks skip important prompts or don't configure the USB as a boot drive correctly. Make sure you choose "USB flash drive" when prompted and follow along with what the tool asks you for.

If your USB isn't booting, check BIOS settings. You might need to change the boot order. Just mash that F2 or Del key when you start your PC to get into the BIOS settings and make sure USB boot is enabled.

If you get an error during installation, like a "Setup has failed" message, it might be a corrupt download. Go back and try creating the USB again.
