Hi everyone

Newbie here just trying to do my part of improving TAILS. I am very
ignorant when it comes to computers and privacy, so no flaming....

Anyways regarding the issue
https://tails.boum.org/support/known_issues/#index7h2 and
https://tails.boum.org/bugs/ThinkPad_X220_vs_GPT/

I have known for a long time now that my Lenvo ThinkPad E320 cannot boot
from USB, so i carry a USB CD drive around with my laptop (something about
UEFI whatever that is). Having no persistence is annoying so I also carry
around a USB as well.
So today I was booting to TAILS connected my CD drive as normal, I rebooted
and forgot i ALSO left my TAILS USB attached to the second USB slot. By the
time it booted to TAILS it asked me for my persistence password. I found
this rather odd knowing that my CD drive cannot have persistence. My USB
stick was also flashing. so i disconnected my CD drive and TAILS continued
to run. I entered my persistence password and indeed it had booted from my
USB. I tried to boot it again without the CD drive it didnt boot. I tried
it again with both the CD and USB attached and each time it would boot to
my persistent USB.

So in a sense accidentally leaving my TAILS USB in allowed it to boot on
the USB, but it won't do this without a CD drive even though the CD drive
can be disconnected when it successfully boots. Is there anyone else with
Lenovo Laptops or UEFI problems (whatever it is lol) that has also
experienced this? Anyone able to test?

I'm not sure how valuable this information is or if the world has known
about it for eons, but I'm just trying to do my part. Hopefully it can give
some insight into a solution even if it's a temporary one. If you need more
information, feel free to email me.
