[CentOS] C8 install problems

Hi all,

I am trying to install C8 from a DVD I made onto a 1Tb disc partitioned into 2 ext4 partitions. 

The first partition contains C7 which I installed via a DVD.

Trying to install C8 yields an error indicating the file /dev/root is missing.

I've checked the SHA256 sum for the ISO for CentOS 8.1 1911 and it checks out fine.
I've burned a couple of different DVDs and get the same error about /dev/root missing from both. I burned both DVDs using the PC app PowerISO. Is that potentially a problem ?

Looking at the log file of the C8 install I see before the message about /dev/root, that the file /etc/iscsi/initiatorname.iscsi is missing 

--and 

/sbin/modprobe -bv sg failed w/ exit code 1

I am doing the install with the target 1Tb disc attached, via a USB cable from a SATA docking station, to a ASUS PC running Windows 7. I boot up via the DVD just fine on the PC, but I've not been able to get past the errors from iSCSI and /dev/root.

I do see a message at the very beginning of the install that the hardware family 12h is "not supported upstream". I'm not sure if that message is important, or a red herring.

Is it possible that the Orico SATA docking station (model 6619) has been dropped in C8 ?

Any tips or suggestions would be greatly appreciated.

Thanks,
