Live USB, x64 & x86?

[JLayneC]

odd question, but I just got a usb flashdrive specific for having Kali linux run offrom. I plan to take this usb and use it on a wide range of pc's some 32bit and some 64bit. So my quesion is, Do i need only 32bit kali on it, or would it be possible to duel boot where i can choose which to run 32 or 64 bit at the time of boot. While i know the eaiest thing to do would be to have 2 seperate usb drives one 64 and one 32, it is a keychain usb drive therefore less is better.

Thoughts ?

The USB Interfce is a bit serial interface, and it doen't care wether the data is 32 or 64 bit compliant.
Once the data is in memory, and you'r ready to execute, the data become more important.
Usually if you have a 64 Bit Machine, you can start by loading the 64 Bit Code, and start de-bugging your application from that point.
Have fun!
