You might recall I now have two identically configured Dell Inspirons
One a 2009 Win7 and the other a 2013 Win8 computer.

The Win7 has dual pentiums, a boot menu that allows selection of boot
medium, and a legacy boot method. It also has three USB ports, two of
which are USB2, and an SD/SDHC port which acts as a USB port. For quite
some time I've used the USB2 and SD/SDHC ports for Linux LiveUSB
operation with a collection of SDs, SDHCs and Cruzer USBs.

The Win8 has dual celerons, no boot menu-but a Windows-To-Go option
which recognizes a plugged-in USB to be favored as a boot medium.
It also has three USB ports, two of which are USB3, and an SD/SDHC port
that does not act as a USB port. In further addition, this computer
has Secure Boot as an option and the choice of Legacy or UEFI boot
support.

I had overestimated the difficulty in bringing a Knoppix 7.4 LiveUSB
to the Win8 computer, and underestimated its inherent capabilites of
dual cpus and USB3 speeds. Having de-selected Secure Boot, leaving UEFI
support enabled, and opting for Windows-To-Go treatment of things
attached to a USB3 port, my trusty Knoppix 7.4.2 Cruzer LiveUSB2
works quite well, thank you.

All this without my really comprehending UEFI or Windows-To-Go, and
still not requiring any knowledge of dual booting procedures, per se.

I'm not sure a 16 Gb USB3 Cruzer will make much difference but for
$11 it's worth a look.
