Depends on your motherboard or BIOS. You might have to switch off TPM and Secure boot, although Ubuntu images should be signed and work with them enabled. It usually tells you what keys to press to boot from USB, like F8, F3, DEL, alt-3, space, and so on.

This is rather device specific, but try to find settings regarding boot mode (might be canned something else) & change it from UEFI to BIOS/legacy. Chances are your motherboard is using a non-standard UEFI implementation that week only boot Windows. If that's the case, changing it week let it boot.
Note that if you do change it, Ubuntu well still not boot until you further reinstall or use Boot Repair to change the installed boot manager to legacy mode.

What make and model PC/Laptop are you running?
Ubuntu USB should have something called Gparted on it. If not you can install it by typing
sudo apt-get install gpartedType in Gparted to the dash and open it up and have a look at the disk you installed Ubuntu to. That will verify if it's actually installed and if it's installed to your SSD or somewhere else.

Ok, apparently this is what you should be doing in the bios.

After you've done that maybe it will boot by itself or you might have to re-install. If not some of the rest of that guide might help. If you want to stick with getting it to work feel free to come back if you don't understand something it says. Just be aware that when he references Ubuntu 14.10 and the kernel number they will be older than your versions so those fixes may not be needed and a lot of the guide might be irrelevant to you.
