Can you try the steps from here:

Critical Boot Issue Please Help

This issue is critical as one of my backups is corrupted, and the other is lost. I have been using Qubes for a little while now, and am dealing with a critical issue. After entering FDE login info, the boot-bar loads very slowly before entering an dracut emergency prompt and displaying: Warning: dracut-initqueue timeout - starting timeout scripts Warning: dracut-initqueue timeout - starting timeout scripts Warning: dracut-initqueue timeout - starting timeout scripts Warning: Could not boot. …

?

And try:
