I still think it's cool that I have what is probably the stupidest setup possible: A _dual-booting, physical-AND-virtual install.
like, sure, you can "dual boot" or whatever, and then select windows or linux when you boot.
but i have it set up so that my computer boots with GRUB, which lets me pick Windows 10 or Ubuntu 20.04; but in Windows 10, I have VirtualBox set up with the actual disk partition, too. So I can literally boot my Linux install in Windows, in a VM, and it works more or less exactly the same.
There are two caveats: one, virtualbox must be started with admin privs, because this is raw disk access; and two, you must update the kernel and bootloader from the real system. (I have a second lightweight Ubuntu install in the VM only, for updating the VM's bootloader; it will autodetect the real install and such)
But outside of that it works flawlessly, and back when I used to use this machine for work regularly I would switch between them pretty frequently.
