dd to copy disk - but then not boot

[Jerry Geis]

I have a PCIe4 disk runs fine.
I got a new PCIe5 disk, put that in the machine.
Booted up the PCIe4.

found out PCIe4 is on nvme1n1 and the PCIe5 is nvme0n1
do I did "dd if=/dev/nvme1n1 of=/dev/nvme0n1"
when done I setup Virt-manager to a new VM with the disk as /dev/nvme0n1
it starts to boot but then bombs out to initramfs

Is there something "else" I need to do for this to run ?

Thanks

Jerry
