I believe the title states what im mostly asking but here's the specs.
Sandisk Cruzer 4GB USB 2.0 Existing OS: Windows Xp Professional SP3
Hardware: Intel Pentinium 4 Xeon Class (x86 F15 M2 S4) [1.8Ghz] IBM Thinkpad T-Series T30
So what I am wanting to do is, Put backtrack onto the usb and run it like the usb was a hard drive. This way it doesnt affect the physical machine and doesnt erase the current OS. Is there a way of doing this?
