Sorry, yes, I know what VirtualBox is. My problem is that I want to access my existing Mint installation through my existing Windows 10 installation. Mint and Windows are on the same physical disc in separate partitions, and I don’t want to have to reboot to do something like export my Thunderbird settings and emails from the Windows client if I’m in Mint.
It’s a temporary stopgap solution while I switch because I have memory issues, and only tend to remember things when I need to use them (probably ADHD related, but that’s another story)
