I'm trying to install Ubuntu on a Samsung ultrabook via a usb stick.

I've tried 12.04 both regular and alternate on 3 different USB sticks but not having success.

The laptop just keeps booting into windows.

I used unetbootin to create the USB image as this worked for when when doing a toshiba ultrabook installation.

I reset my Boot Menu to be

4 SATA HDD SanDisk SSD u100 128GB

Then F10'd but no success, still boots windows.

I've tried changing UEFI boot support to be enabled and I've tried changing PXE OPROM to be enabled but neither has helped.

Not a duplicate of that question. See my answer – Michael Durrant Sep 15 '12 at 0:27
In Series 9: 1. In BIOS set: USB HDD as the first option in Boot Priority 2. Change Fast Bio Mode to disabled. If that doesn't work try other USB pen. – Klaatu Verata Necto Aug 30 '13 at 13:13

** -----> Found it! <----- **

The fix was pretty obsure and I had to test it out a bit to be sure.

Given how strange it was this may well help others who are stuck!

  • Reboot with f2 pressed.

  • Wait 10 seconds until you can use the left/right keys to change boot.

  • change the boot order putting the USB items first (3 in my case). Use f5/f6 keys.

and then...

on the advanced tab settings...

  • Change `Fast Bio Mode' to disabled.

  • Change USB s3 wake-up to enabled.

  • F10 to save and it will...

  • boot into Ubuntu from the USB key.

This took me 2 days to find!

After that, changing usb port worked for me – Yekmer Simsek Feb 8 '14 at 11:35

For me it worked by disabling the Secure Boot in the BIOS

I did this and it wasn't the fix. – Michael Durrant Sep 15 '12 at 0:27
Sorry, my answer was too brief. The issue was EITHER (a.) Needed better USB install media; OR (b.) Needed to manually force BIOS-boot to choose ONLY the correct device. Your method achieved a variant of (b.), by making boot-order (notoriously unreliable) work correctly. – david6 Sep 15 '12 at 1:18

Had the same issue, and I solved it (searching for 3 hours) by disabeling the boot on the HDD with CTRL + 1 in the boot sequence !
