You can use it like it is or install it to multiple systems of your choice.
BlackArch Linux is an Arch Linux-based distribution for penetration testers and security researchers. The repository contains 1600 tools. You can install tools individually or in groups. BlackArch Linux is compatible with existing Arch installs.
I take pride in my work, if you want a USB Drive that works and Boots, this is the right one for
you.
BlackArch Linux can be ran from this live USB installation (if your PC offers a
‘boot from USB’ option. You may have to press a certain key at boot time
or modify your bios settings to change the boot order). Since you are
booting and running from the USB drive, your normal hard drives will be
untouched.
Since
this USB device has had the custom Linux distribution image copied on
to it, it will not be sealed in the original packaging. I will ship fast and with care. This is a PRO tool please use with respect and care.
