Solved thanks to Reddit user liwindowsnux’s comment under a post by someone experiencing a similar problem on r/RockyLinux.

  • You’ll need a tool (such as Rufus) to burn the installer ISO into the USB stick in ISO mode (not dd mode) to get access to the /<USB_Stick>/EFI folder. I guess you can also use dd mode if you can get access to the EFI partition.
  • After the burning process, backup /<USB_Stick>/EFI to somewhere else just in case.
  • Get into /<USB_Stick>/EFI/BOOT, delete the original BOOTX64.EFI and BOOTIA32.EFI.
  • Rename grubx64.efi and grubia32.efi to BOOTX64.EFI and BOOTIA32.EFI respectively.
  • Boot your system with this USB stick in UEFI mode and you should be able to boot into the installer.
