Let me start by saying I am not concerned about messing something up and everything important to me (data and OS wise) is backed up many times over. That said I plan to go full machine Zorin install after running a few test installs and "taking my lumps" through a learning curve for a few weeks. For now I have a decision to make before wiping it all away and going to Zorin in a couple of weeks. Choice: 1. Place Zorin on a spare partition that I have available, but this config presents another simple hurdle that I have to jump. I can easily install Zorin on this partition BUT I'll need to create a simple boot flash (grub) so that I can mount Zorin using the flash. The machine in question is fully TC encrypted other than this small partition and I don't want to mess with changing the bootloader on the drive. I am curious as to how the speed will compare with a regular install. Since Zorin is actually installed on the sata and I am mounting with the flash, I suspect it will operate at great speed. This will be a decent machine running either an i5 or i7 chip with 4-8 gig of Ram. I have two to choose from. 2. Place Zorin on a USB 3 external drive and boot from the same flash as above. I'll need to confirm Zorin actually connects at USB 3 speeds, but if it does I suspect the speed would be decent there also. 3. Use a USB 3 flash (32 - 64 Gig) and install Zorin completely on that. I am not too fond of this idea but it would be simple to do 4. VM - I am not interested unless that is an absolute beginner starting point. I have used VM's for years with BackTrack. I would be interested in hearing some advice mostly on the comparisons between choice 1 or 2, but I am open to others as well. Again, this is temporary until I gain the confidence to go full on Zorin or other distro's as my skill advances. Would the performance/speeds be good using option 1 or 2? Advice?
