Long story short (you can read the [-] points after the main body):
In some cases like mine, the MOBO has a ReBar setting (with 4G transfer or whatever) where I can’t install OSs outside of the NVMe, and I don’t want to install W10 (or even 11) on it because it takes 110gb just to function.
I wanted to install it on a 240gb SSD, but it didn’t work[1].
SINCE[2] installing it AFTER Linux isn’t really easy or friendly[3] I tried to install it before, but it refused to use the NVMe for the EFI partition and the 240ssd for the OS (probably because of Point 1).
So my point is:
Could I use a VM software to use the 240gb ssd to install W10 without any encryption or whatever, literally just a raw install, and then add it to Grub2 later?
I mean… I COULD use a second computer to install W10 on that SSD there, and then try to move the SSD on my main computer… but let’s assume I can’t do that both because “software labor is easier than physical labor” and because most people have just and only 1 computer, so they’d not be able to do this.
I could have tried to “install W10 on the SSD before activating ReBar, then install Fedora on the NVMe, and maybe Grub2 would’ve been able to catch the W10 installation”… but now it’s too late, I don’t want to risk screwing up my Fkde installation for the chance to reinstall something I don’t really need…
I use W10 for comparative benchmarks, and with this PC I’ve basically already recorded most of what I need. ↩︎What a funny word… “since”… ↩︎
You need to read the previous posts for the complete context, installing W10/11 after Linux makes W eat Grub2’s priority (making it just boot into W), requiring Linux to be reinstalled (infinitely easier than “fixing” whatever obscure problem was created, since normal people like me can’t know). ↩︎
