[Bug 560464] Re: "acer-wmi: Unable to detect available WMID devices" on boot

[Markhor]

This isn't a usual failure, maybe a hardware problem... You should
better start a thread somewhere at forums.ubuntu.com.

Reinstalling the OS from scratch is always a good idea.

As for the live USB, during BIOS screen, enter the boot devices menu
(press F2) and make sure that boot from USB is higher than from HDD. I
don't remember exactly about F2, maybe you have to enter the BIOS menu
itself and change the boot device order there. BIOS screen displays what
key you should press. After changing that I was able to install Lucid on
my AOD250.
