Ubuntu 18.10 install from USB on a Dell Optiplex 7040 Micro. I was
getting the same error (mostly), but here's what fixed it for me...
I had a USB flash drive with the installation on it (followed directions
from https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-
on-windows#0).
Hello
One possible cause may be forgetting duplication of the directory

Hi all,
I've got a fix for the iMac 2009 I tried to install Ubuntu on. I had the
same problem and the boot config fix didn't work. The instructions from
Ian Allen (comment 19) did not work initially - I got to the initramfs
prompt and waited for the usb device to show up with the ls -l /dev/sd*
In fact, the installer works without the grub configuration hack if I
just use a USB port with enough power! Just selecting the boot device
from the rEFInd menu worked with the other USB port.

Hello Ian ,
I have tried as you up to adding break and debugging to booting parameters.
Then I have tried ls /dev/sd* and same its not showing sdb. I have waited for
sometime
But its still not happening.
So just my curiosity forced me to remove USB even system
Simple fix on grub4dos:

Unfortunately my bios doesn't have an option to disable floppy drive

this problem from people with notebooks without this option too.

This is in fact a bug in casper, and not a dupe of #492301. The error

I burned the same ISO to CD and the booting was different from the
beginning... the installer menu had different options etc. And it works.

It happens with Karmic as well on an USB. But only on a selective pc.
However if you wait like 5 min or more it should boot fine.
