When powering on, hit the f12 key to bring up the boot menu, and see if it
shows up there.

Try different USB ports, and a different USB stick if you have one
available. I am finding many search results for "lenovo x220 boot from
usb" which seem to indicate it is a somewhat common problem. You do have
to make sure that you have the USB bios support enabled in your bios, or a
similar option, but seeing as you already have Kubuntu on your current
drive, I will guess that you booted from a USB stick for that install?

Also, I mentioned trying another stick, as a few of the reports mention
Sandisk sticks specifically, so they may be problematic. Some of them come
with hidden partitions for backup utilities, etc, and this may prevent
them from being bootable Linux discs.
