Build up a QubesOS from source - with -mtune=native -march=native CFLAGS, it will let you use all your CPU can offer, which is essential to 32-bit arch: Intel or ARM. If your CPU is unable to provide any kind of hardware virtualization - then take a look at eBay and/or Amazon for a second-hand devices. It will pay you back greatly!
The issue is not OS-dependent, it's how the hardware works. You need to examine the following in your BIOS(it may need updates if you have an old one):
Is the legacy boot enabled? If not, the USB drives will not be among the list of the devices that are searched at the very first phase of the boot-up process to look for an operating system loader
Is your ...
Well, first of all - remember, that Tails is Linux by heart, so - basically - there's an attack vector for gaining access to all the hard drives attached. If you want true anonymity - unplug it when you're using Tails : physically or via BIOS. Where to save data - it's totally up to you: Tails is Linux, so just mount it and use it
I do recommend you QubesOS instead of Tails, but the requirements are basically the same:
At least a dual-core chip with true two cores, i.e. don't forget about Intel HyperThreading's virtual cores
At least 8Gb of RAM. Yes, 8 - and not 4 or smaller, because you need some RAM for your regular tasks to run smoothly
256Gb fast SSD - so disk will not ruin your ...
Tails is still immature, so no wonder why you're having the trouble you're asking about. To achieve a way better security and user experience you need to use QubesOS and Tor combined - try it and forget the Tails(hit) :) To make things really secure you arise Tor not at dom0 as it said in many quickjump guides, but on a separate VM container and then you're ...
