Solution:
Alternatively wipe your disks properly:
Grab this distro https://grml.org/download/
Terminal these commands:
Wipe all sata disk
sudo for i in /dev/sd*; do if [ "$i"!= "/dev/sdX"* ]; then wipefs -af $i; fi; done
Wipe all nvme disks
sudo for i in /dev/nvme*; do wipefs -af $i; done
Then try flashing fydeos again clean and installing it.
