No need for any changes to your existing PC or to get a second PC to use TOR much safer. I built an independent isolated bootable USB TOR stick using Linux installed on it as a full read and write OS along with the TOR browser. You just have to make sure that the internal drive cannot be mounted at all when using the stick. This stick will then be seen as a stand alone PC and the only drive on the system. It is a whole system in it’s self and just borrows the hardware. So if anything happens it can only happen to the independent isolated stick.
I’m only vaguely familiar with TOR. What are the issues surrounding it? Why should one worry using it?
In the near future, I am getting a new thinner laptop the current one is old, make the new one my main computer...
Re-image the current laptop with linux, install TOR..
I’m uncomfortable in combining TOR and the Dark Web on one machine, even if it’s safe, I just prefer to keep things separated
