Did you make sure that the of
is correct? lsblk
to make sure.
If your sure it wrote to the right drive i would make sure that you have a good download. Did you run your checksums?
I think fedora works with secureboot but you might want to disable it just to see if that is the issue. I believe you can reenable it after install.
Make sure to go into the bios and boot from external drive/usb.
Out of 15 years of using dd
i have never had a problem.
You might not have done anything wrong.
There is also the possibility of a bad USB drive or write memory failure. There is lots of things that could go wrong that’s not your fault. Might try a different USB or a different USB port on your machine.
You might want to try zeroing out the USB,
if=/dev/zero
. Then you might need to make a new partition table. You can use something like gparted. Or https://linuxconfig.org/how-to-manipulate-partition-tables-with-fdisk-cfdisk-and-sfdisk-on-linuxYou can try GPT or DOS. I dont think it matters.
Not sure if the ISO will have the partition table so you might want make the new partition table just to be sure the stick defiantly has one. If dd overwrites it from the iso no harm no foul.
Thats all the troubleshooting steps I can think of right now.
