From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

When I was still dual-booting Windows and Linux, I found that "raw disk" mode virtual machines worked wonders. I used VirtualBox, so you'd want a guide somewhat like this: https://superuser.com/questions/495025/use-physical-harddisk-in-virtual-box - other VM solutions are available, which don't require you to accept an agreement with Oracle.
Essentially, rather than setting aside a file on disk as your VM's disk, you can set aside a whole existing disk. That can be a disk that already has Windows installed on it, it doesn't erase what you have. Then you can start Windows in a VM and let it do its updates - since it can't see the bootloader from within the VM, it can't fuck it up. You can run any software that doesn't have particularly high graphics requirement, too.
I was also able to just "restart in Windows" if I wanted full performance for a game or something like that, but since Linux has gotten very good indeed at running games, that became less and less necessary until one day I just erased my Windows partition to recover the space.
And probably disable quick boot as I'm guessing the kernel is going to get pissed when you suddenly switch between virtualization and native
I've never run a virtual machine, because I've always had, frankly, really shitty laptops. Like... Cheapest of the cheap without being a Chromebook. Only decent computer I've ever bought got broken within a month. :(
Can I run VMs on really low end specs? The screenwriting software is the only thing I need it for, and I'm assuming it's pretty much the same as running a word processor.
Provided your CPU has virtualization features (described here) then the performance overhead for virtualization is negligible. So very probably you'll be fine.
The memory requirements for virtualization is not negligible.
That depends, if you're going to run a barebones W10 install with what amounts to a word processor I think 2GB should be enough. If you can run Chrome you can run a VM. 4GB if you're feeling generous, that's a fair compromise as compared to the disadvantages of dual booting.
I remember trying to push the limits with a Windows 10 VM, and 2GB was the bare minimum;
however, Windows loves to abuse virtual memory (basically using the main storage drive instead of RAM) and if that drive is a HDD the PC is little more than an IoT space heater.
A relative of mine has a Windows 10 PC with 4GB of memory and it takes ~ 5 minutes to start Chrome after booting it up; it does have a lot of miscellaneous bloatware on it, though.
