The behaviour you describe I guess is due to have the "Fast BIOS Mode" option enabled in your BIOS. When this option is enabled the boot preferences are ignored. Try to change it to disabled and then select "USB HD" as your first option under "boot device priority". Nevertheless, there exists some bugs related with ACPI on Samsung laptops (it affects Ubuntu and other distributions, even with Linux mainstream kernels).
