I have a laptop, originally installed with Windows 10, and it has a second internal disk. I've installed Ubuntu 18.04.2 on that disk. When the computer starts up, Grub gives me the choices I need for dual booting. That part all seems to work fine.
What I'd like to be able to do is to boot from that same disk in a virtualized environment, ideally VirtualBox or Hyper-V (because no cost to me). At the moment, I've been trying to get this going in Hyper-V, and have a VM defined with access to that physical disk. But it won't boot. This is unsurprising as the disk wasn't setup to boot.
Is there a way, from within my Linux environment perhaps, to install GRUB to that disk so that it would be bootable? I may be naive here, but I think that's all I need, or at least the next major step.
This Linux disk has 2 partitions on it -- one is the large (223.55 GiB) Linux partition (ext4), but before it is a small (15.98 MiB) Microsoft reserved partition (unknown fs), that I believe I can delete, because I have no need for Windows to access this disk.
Also note that I don't want to mess up the original HD in the laptop. I want to continue to be able to dual-boot, but would like to be able to run Linux virtualized because most of the time that will be sufficient for my needs.
Thanks for any help!
