I recently bought a new laptop (Acer Aspire One Cloudbook 14) and wanted to install Ubuntu (14.04.3) on it. I put it on a USB following this guide: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows
I erased Windows 10 and installed Ubuntu. I honestly don't remember how the installation initially went as I have been trying to fix this issue for over 12 hours, I know it didn't go too smoothly, as I remember the screen showed a few errors during installation but it eventually loaded, and other than the touch pad not working, it seemed fine.
On the reboot however, I was unable to even log in.
BOOT MODE: LEGACY
If I have the boot mode set to Legacy, it takes me to a GNU Grub thing if my hard drive is highest priority in boot order, listing a few options (see the picture bellow).
If I select Ubuntu, that is when I get the messed up screen and "Kernel panic – not syncing: IO-APIC + timer doesn't work" error.
If I have USB as highest priority (again in Legacy mode) it takes me to the installation menu, though I suspect it doesn't look the way it is suppose to, but that's how it looked when I first installed it, the difference now is, whether I select install Ubuntu or try without installing, I get the same kernel panic error I mentioned earlier.
BOOT MODE: UEFI
If I run it in UEFI mode, it says "No bootable device" whether my hard drive (or whatever the equivalent is on this laptop) or USB is priority.
I believe I installed Ubuntu in Legacy mode by accident, which maybe caused this issue?
I have been searching online for many hours, but could not find an issue that was close enough to mine, and already tried many of the solutions of problems that were similar. Like disabling secure boot, trying different boot modes, and nothing is listed if I try to select a trusted UEFI file when hard drive is priority, if USB is priority, it just lists files that are on the USB, none of which can be selected.

Assuming you have booted in legacy mode, installed via USB, and are now trying to boot up your freshly installed Ubuntu 14.04. then:
The correct boot alteration as detailed here in the Arch wiki
Is to add the following parameters to the file
/etc/default/grub

This worked for installing Ubuntu 14.04
If having trouble booting up initially, press e at the boot options (GRUB) menu and add the parameters at the end of the line with
