How to make a bootable USB
Download the ISO for NVIDIA if you have a GeForce card, or AMD and Intel if not.
Check the file
When the download finishes, compare it with the checksum published next to it.
AMD and Intel checksum NVIDIA checksum
On Linux, in the folder with both files:
sha256sum -c WASD.iso.sha256
On macOS:
shasum -a 256 -c WASD.iso.sha256
On Windows, compare the result with the text in the checksum file:
certutil -hashfile WASD.iso SHA256
For the NVIDIA disc, use WASD-nvidia.iso in those commands.
Write it to a USB stick
Use a 16 GB or larger stick.
Use a free tool for the computer you are on. It will erase the stick.
Windows
Fedora Media Writer or Rufus. In Rufus, write the ISO in DD mode.
Mac
Fedora Media Writer or balenaEtcher.
Linux
Fedora Media Writer or balenaEtcher.
Boot it
Restart the PC, open the boot menu, and choose the USB stick. The menu on the stick says Start WASD.
