This question already has an answer here:
I'm getting myself a laptop for pen-testing using VMware etc. Theoretically speaking, if I were to replace the disk drive with a secondary hard drive, could I successfully set up the laptop to run off of each hard drive as though they were separate computers.
Ideally, what I'm looking for is a way of keeping my security pen-testing lab separate from my iTunes/email etc. to minimize risk of any viruses or whatever getting onto my other hard drive.
Is this something that could work, and is there a way I could set up my new laptop to ask which drive i'd like to boot from at start up so that I can essentially have two separate machines in one?
Similarly, could this work if I only had one hard drive in the machine at a time (to keep all the personal stuff that may have details etc safe from any damage I may do by accident).
Ultimately, all the work I do will be done on virtual machines, I'm just worried that I may accidentally do something that then leads to any account information I hold on the laptop being compromised or something?
