If you have a linux system already then we recommend just using dd to copy the iso file to a USB stick.

...but win32 diskimager is fine, too, since it also makes a 1:1 copy of the ISO file to the flash drive.

Diskimager is indeed mentioned in https://wiki.centos.org/HowTos/InstallFromUSBkey
(but not the only tool)

Here are the approaches that worked for me, as I have had to set up CentOS on ~10 machines.

Beware that Rufus also breaks our iso images depending on the options selected. I believe there is an "iso" mode that works correctly but I'm not sure it is the default mode.

Rufus is just one of the many old-age and obsolete tools from old times when you couldn't boot a Linux iso image from a USB stick straight ahead. These times are long gone. (I cannot even remember when Fedora and other Linux distributions have switched to hybrid ISO images. Was it about 10 years ago?)

I cannot see why such tools are still used or even recommended.

I wouldn't call Rufus obselete, given that it successfully fixes a specific problem:
  • Lets you create a CentOS 7 bootable ISO USB from Windows 10

But you need to use it with specific settings to fix that problem successfully, i.e. switch all the ISO manipulation stuff from Rufus off. So why use it in the first place if there are Windows tools like the "Win32 Disk Imager" or the "Fedora Media Writer" available for MS-Windows which don't offer ISO manipulation, i.e. increasing the chance for success significantly?

Like TrevorH said: "Rufus suffers from the "I'll be clever and rewrite the image" problem". It's an application to rewrite ISO images, and therefore Rufus is obsolete since Linux ISO don't need to be rewritten for a decade. Yes, using specific settings you could do 1:1 copies as well, but this does not make it the right tool for the job. Libre Office Writer can write plain text files, too, but would you recommend it as great tool for editing plain text files like ~/.bashrc?
