Start Job Is Running for Hold Until Boot Process Finishes Up 18.04

On power up, can you press ESC or DEL or whatever key sequence gets you into the boot manager? I upgraded a LattePanda running lubuntu 16.04 to 18.04, and it was looping through some failure sequence. When I pressed ESC and entered the boot manager, I found that the first item in the boot sequence was an entry for Android. I don't have Android installed on this device, so I don't know how or why that entry was there. I selected the override to boot ubuntu, which worked fine. Once in the ubuntu O/S, I entered the following, based on info I found in another post:followed by:which told me that the Android entry was #5, so I then entered:to remove that entry from the boot sequence so that the next time I powered off and back on, it went to ubuntu.

Hope this helps.

I just installed ubuntu-desktop 18.04 on a new machine (no OS was previously installed). When I restart after installation completes the boot process gets stuck with

Started hold until boot finishes up.

Pressing CtrlAltF2 or F1 does not do anything.

When I go into the recovery screen, the keyboard does not respond...

Any ideas how to deal with these issues?

Thanks!
