I have an old laptop which I use on college. An i3, 8GB, 1TB HDD (5400rpm) and a 120GB SSD. I have a Windows 2016 running on the SSD, which uses about 90GB of that drive (OS plus other software). Since I need to use some Office tools, I can't simply uninstall it. However I'm also trying to use a Debian based OS (Pop!_OS, by System76), so naturally I dual booted the hell out of it.
I've installed the Linux based OS on the HDD, but not surprisingly it's as slow as I expected.
I do want to install both OSes on the SSD, although I'm pretty sure that I can't fit both on those < 120GB.
Is there a way to put only the Linux 'core' on those 30GB and all of the less accessed files on the HDD?
I have no problem re-installing Linux since it's a fresh install.
Are LVMs the solution for this? Should I set the root to the SSD and everything else to the HDD?
