I tried to install Ubuntu 19.04 via USB-Boot on my new notebook. It is a new Acer Nitro 5 with its own Linux (Linpus Lite) system. But whether this already setup Linux boots nor the USB device with Ubuntu 19.04 that I just made. The shipped system just boots into a bash like this:
[root@localhost /]#With the bootable USB device it is a little bit different: After choosing any option of the GRUB menu the screen sometimes just stays black with no signal of activity at all. The other times it shows a couple of watchdog errors like described in thisBug Report.
I tried to edit boot options like mentioned in the answers to the bug report, but this didn't work for me. I have to add that I have no plan what exactly happens with/without those boot options. I tried to add:
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
didn't work
ro rcu_nocbs=0-7 ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 quiet splash vt.handoff=1
didn't work, too
I turned off secure boot already, and the virtualization options, too. But this also had no effect. I searched the web for two days now without finding a working solution, but I've seen posts of person who did manage to install Ubuntu on an Acer Nitro 5. Unfortunately they asked about different problems in this forum. see here
Any ideas or help?

SOLUTION:
in GRUB menu pressing 'e' and adding
pci=noacpi
after 'quiet splash', booting with F10 worked fine. Solution from here:

It looks like Acer Nitro need pci=noacpi boot parameter. Many systems need one or several boot parameters. If nVidia nomodeset parameter required.

Most new system, even though new, need UEFI update from vendor and if a SSD firmware update to SSD.
Acer also needs "trust" setting in UEFI for ubuntu entry. Acer Trust Settings - details, some now report that then secure boot has to be on to set trust:

Acer Aspire E15 will not dual boot, many details Trust settings in step 35
