If using dd for Windows, run dd -list and look carefully at the list of NT Block Device Objects and use the one that looks like \\?\Device\Harddisk1\Partition0 where the description is something like Removable media other than floppy. If using a version of Windows newer than 7, make sure you unmount the USB drive first (formatting it prior to launching the disk copier is one way to accomplish that), otherwise Windows might refuse to write on the stick, bailing out with the "can't write to drive" error message.

On linux, use the sha256sum command to do the same job. It will basically be identical to a usb made with any other direct image tool such as dd or BalenaEtcher. On Windows you can use the command certutil -hashfile c:\Users\JDoe\Downloads\CentOS-x86_64-dvd1.iso SHA256 to perform this checksum. The usb will be a clone of the iso, it will not be fat32, it will not have any persistance or save file. You should check that your downloaded copy has a sha256sum that matches the published one to eliminate corrupted media install problems. These can be found in the release notes for each new version and also in a text file located in the same directory that you obtained the iso image from.
