• Rufus message, when trying to transfer a RHEL, CentOS, F, openSUSE image to a USB stick:

  The image you have selected is an "ISOHybrid" image.
  (_) Write in ISO Image mode ( Recommended ).
  (x) Write in DD Image mode.

• I selected “DD”.
• With “ISO” for “CentOS Stream 10”, there is the error message:

  GRUB loading.
  Welcome to GRUB!
  error: file '/boot/grub/i386-pc/normal.mod' not found.
  Entering rescue mode...
  

• Rufus message, when trying to transfer a “CentOS Stream 10” image to a USB stick:

  Rufus detected that the ISO you have selected contains a UEFI bootloader that has been revoked and that will produce a "Security Violation" screen, when Secure Boot is enabled on a fully up to date UEFI system.

• reddit "r/CentOS" - "CentOS won't boot on secure boot" - “Revocation of UEFI bootloaders happens all the time and CentOS Stream 9 was released in 2023, so, yeah, it happens to be using a UEFI bootloader where vulnerabilities have been found and that has therefore been revoked, hence the message you see in Rufus. One would have expected CentOS to at least have released an updated version of CentOS Stream 9 that uses a non-vulnerable bootloader, but it appears they haven't done that”.

• Rufus message, when trying to transfer a “CentOS Stream 10” image to a USB stick, for the first time:

  The image uses Grub 2.12-nonstandard-gdie but the application only includes the installation files for Grub 2.12.
  As different versions of Grub may not be compatible with one another, and it is not possible to include them all, Rufus will attempt to locate a version of the Grub installation file ( "core.img" ) that mateches the one from your image.
  
  - Select "Yes" to connect to the Internet and attempt to download it.
  - Select "no" to use the default version from Rufus.
  - Select "Cancel" to abort the operation.
  
  Note: The file will be downloaded in the current application directory and will be reused automatically if present. If no match can be found online, then the default version will be used.

• I selected “Yes”.
