I'm looking to finally use Linux properly and I'm planning to dual boot my laptop. There's enough storage to go around, and while I'm comfortable messing around I'd rather not have to run and buy a new device before school while fixing my current one.
This was the general guide I was planning to follow, just with KDE Plasma (or another KDE). I was going to keep windows the default, and boot into Linux as needed when I had time to learn and practice.
I assume it should be the near similar process for KDE Plasma?
I'm ok with things going wrong with the Linux install, but I'd like to keep the Windows install as safe as possible.
Some day you may find your machine booting into linux without displaying a grub menu. You were promised a menu giving you boot options. Where is it? The problem may be your grub timeout is 0. Set the timeout in /etc/default/grub and then run update-grub. See section 6.1 of the info grub manual.
In the same config file, you can also re-enable the "OS Prober" setting, which was turned off in some distros by default, which can also cause windows to not be displayed.
I'm not sure which distros have overridden this option to being back on by default on new installs, since AFAIK it was changed upstream.
