Articles say "bring your secure pc everywhere" when they talk about secure distros on an USB, easy to say though...
With 32bit, 64 bit, BIOS, UEFI, Secureboot and any mix of them how do you guys do it?
I have been travelling with an USB with Tails and it was unuseful, rarely booted (either refused to boot or the USB wasnt seen at all), one of the times it booted I even found out there was no way for me to connect to the net without asking for the password at the counter (was it the MAC changer?) so I just gave up using it.
In the places I travel to I find a mix of old and new machines, its already difficult to reboot them without people noticing so its almost impossible to go changing BIOS settings to make things work.
I know I could bring a cheap netbook but in some places I would be noticed way too much and in others its just inviting for trouble (mugged)
Im not an activist or anything too particular, Tails its a bit overkill, I like some features of Tails, some of IprediaOS, I used Puppy in other occasions and as ready to go it was handy (but not as secure as the others)... I have been looking at Tinycore, to add the features I like of the various other distros but so far I am banging my head on a wall as even at home on one computer I still have to toggle the legacy BIOS on and then back off when I am done and it doesnt work at all on my other pc (so I burned Tinycore but installed nothing on it).

Maybe these are all stupid questions due to inexperience but am I missing something obvious? Is there a way to have different distros version on one USB and boot the one that works? Do you guys know of some sneaky way to go rebooting and changing bios setting without being too obvious?

I think AntiX live will boot on both BIOS & UEFI systems, & it can be loaded to ram, which could be useful, as well as many other options.

Thanks, I'll give a look at it

I'd just go with Tails. It's easy enough to use and comes stocked with nearly all of the programs you might commonly use. If you use a larger USB stick then there is also quite a bit of space in the persistent partition.
