Problems installing QubesOS on Samsung Gateway from bootable external hard drive

Set up qubes on external hard drive to boot upon launch. Downloaded from www(dot)qubes-os(dot)org

Installer itself boots fine, proceeds with install, but then I get these errors:

[ 215.94..... ] dracut-initqueue[649]: Warning: dracut-initqueue timeout - starting timeout scripts [ 215.94..... ] dracut-initqueue[649]: Warning: Could not boot [ 215.94..... ] dracut-initqueue[649]: Warning: /dev/root does not exist Starting Dracut Emergency Shell.... Warning: /dev/root does not exist Generating "/run/initramfs/rdsosreport.txt" Entering emergencym ode. Exit the shell to continue. Type "journalctl" to view system logs. You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot after mounting them and attach it to the bug report.

And when I enter journalctl I get a thousand line report.

Laptop: Samsung Gateway 700Z series.

Let me know which more data should I submit to help troubleshoot and find solution to this problem.
