I have never used VMWare. I imagine that it must be very similar to VirtualBox.
The way that VirtualBox works, it does not create a partition. Instead, it creates a “Virtual partition” merely by taking up space on your hard drive. You should not need to create any new Drive Partitions if using a Virtual Machine.
Whether you are installing on the drive or installing in VirtualBox (And probably, this is the same in VMWare), you must set the Mount Point- that is usually Root. The default is just “/”.
To make that make sense, first picture a Directory tree in your mind. At the very start, you have One Basic Directory that contains everything else.
A directory starts with “/”. So that topmost directory that contains everything else is Just /
Then we look at contained directories: That is the Path.
For example, let’s say you install Vivaldi Browser on Linux. This is installed into the opt directory. The Path to the Vivaldi launcher would then be
Vivaldi.bin is contained within Vivaldi Directory that is contained within opt which is contained within root (/). Each file on the path branches out from that one base directory. Well… An upside down tree. Kind of like a phylogenetic tree.
While the above is a Linux example; it is actually similar on Windows- with different names on things (And Windows also has a registry).
If VMWare is anything like Virtualbox, it is tedious with lots of settings. LOL.
There are whole forums devoted to both, helping users learn how to use it and troubleshoot or tease out settings issues.
Installing on either means that the Linux OS you would like to test is not physically "installed’ on your system and is run and contained entirely within the Virtual Manager. From boot to shutdown. Booting in VM is an initialization routine, instead of a boot routine,. so all actual booting is managed by either UEFI or BIOS / MBR for the Installed System, in your case, Windows.
VirtualBox or VMWare can be a very useful tool as it ‘sandboxes’ or contains the Test Software or Test Operating System, preventing errors from affecting your system. It is also not for the faint of heart… It is a complex piece of software and in my opinion- finicky.
I have created a partition on my drive that exists solely for testing. I physically install distros or operating systems on that (Ok, actually, I have Two… one is a static OS for testing Software and one is for testing OS’s…) as I find it is more stable, reliable, easier to manage and easier to install.
