I downloaded Fedora-Workstation-Live-42-1.1.x86_64.iso and followed directions to check the checksum. dd'ed the file to /dev/sdf . At the time, that was a USB adapter for an SD card. cp'ed /dev/sdf to f1.iso . cp copied more than was dd'ed, so I interupted it. cmp told me Fedora-Workstation-Live-42-1.1.x86_64.iso was an initial string of f1.iso . When I tried to boot from the SD card, I got Trying to boot from CD-ROM Trying to boot from USB device GRUB hang I have also tried using the boot menu. When I tell the boot menu to use the USB device, it doesn't. It just boots from the hard drive as if that was what I told it. What is going on? What do I try next? -- Michael hennebry@xxxxxxxxxxxxxxxxxxxxxx "SCSI is NOT magic.
