Hi there, I am trying to figure out how to run Gentoo and Windows 10 simultaneously and hoping you all might be able to give me a few hints on how I might run each on their own physical ssd drive. I haven't installed Gentoo before, only Archlinux, and have been planning out how I can keep getting work done with Windows while taking my time setting up Gentoo. If I can install Gentoo through VM from Windows, I would be able to work on Gentoo gradually and if I can install Gentoo directly to a separate physical ssd, I would be able to eventually just dual boot into it.

I so far understand mostly how to install Gentoo into a VM environment, but I haven't yet figured out how to install Gentoo directly to a separate physical ssd so that I can run both Gentoo and Windows 10 simultaneously while also being able to dual boot when I don't want to run an OS in VM.

After I figure out this direction, I will want to figure out how to run the pre-existing Windows from a VM hosted on a Gentoo VM so that I can boot into either OS, then fire up programs I need on the other through VM.

Thanks for your time. I hope I have explained my goal sufficiently so as to not waste any.

Eckomute,

Welcome to Gentoo.

The details installing directly to a HDD from inside a VM vary between virtualisation solutions.
I think Virtualbox can do it but I cheated.
I made an image of a laptop onto a HDD then booted the image in Virtualbox.

Moving from Virtualbox to bare hardware will need a few changes to make it work but its doable.

I read your post as suggesting that you wanted to run a VM inside another VM.
You can do that but its very slow. The HDD image I created, was Windows. It had Gentoo installed in Virtualbox.
When I ran the Windows install in VBox on Gentoo, I just hat to try the Gentoo install inside Windows, inside Gentoo.
It was very very slow.

Sorry for my miscommunication. I don't want to run a VM within a VM. I have two physical SSDs where each OS will be installed. I can remove either and run its OS. Conversely, I would be able to boot up Windows on one of the physical drives, start up a virtual manager, then run the Linux located on the other SSD.

Initially, I want to boot up Windows, open a VM, then install Gentoo to a second empty physical SSD directly if possible.

For clarity, there are two main goals here:

1. Installing Gentoo from within Win10 (SSD1) directly to the physical SSD2.
2. Running the installed Gentoo (SSD2) from within Win10 (SSD1) in a way that modifications are committed on the physical drive rather than to only a virtualised copy.

Eckomute,

That's fine. Linux, not just Gentoo, has video drivers to get the best out of Virtualisation.
They will not work on 'bare metal', so you might want to install both and switch as required.
Likewise, the hardware will appear to change between the Virtual System and the real hardware.
Your Gentoo kernel will need to work in both places.

Step 1. Install Virtualbax (or whatever you want to use) onto Windows 10.
Step 2. Create a Virtual Machine, using SSD2. (for gentoo)
Step 3. boot the VM with a System Rescue CD ISO image in the virtual CD drive.
Step 4. Install Gentoo

System Rescue CD is more user friendly that the Gentoo minimal CD.
