I did the dd if=CentOS-8.1.1911-x86_64-dvd1.iso of=/dev/sdd to a 16G USB disk then tried to use it on an install. The installer said invalid install media. Any way to verify if the "write" to disk was good ? I got no errors on the dd. I did re-download the iso and did a diff and there was no diff. So I think my iso is OK. Jerry
Well after a closer look - Seems like the OLD 8.0 iso image is still on the USB. Not the new 8.1 I have tried to redo the dd command to copy the 8.1 iso - I get no errors - but it still comes up with the 8.0 I then tried to remove the partitions, save and recopy. still same old boot menu. Is there a trick to write over the UEFI stuff ? Jerry
What's your dd command? Are you sure you are writing to the raw disk and not inside a partition?
