today I tried to install ubuntu on my computer (Lenovo Idea Pad Intel Core i7-8565U BIOS-Modus UEFI). I opted for a dual boot configuration. During the installation I received a message saying:
This computer uses Intel RST (Rapid Storage Technology). You need to deactivate RST before installing Ubuntu. For instructions, open this page: help.ubuntu.com/rst.
So I did, I entered the settings by pressing the F2 key during startup and then I switched from "RST mode" to "AHCI mode", as shown in this image. Ubuntu was then installed without problems. Now I have three questions. But first I would like to point out that I am not an expert, so I apologize if they may seem trivial or stupid.
- What are the implications of this change of settings? Is efficiency affected in any way?
- Every time I start the pc I have to select the operating system I want to use. If I use windows I am forced to use the RST configuration, unlike Ubuntu which only starts with the AHCI configuration. Every time I start up I have to change the settings manually or is there a way to automate the procedure?
- This is perhaps the most important question. Initially, when Ubuntu asked me to disable RST mode, was it the right procedure to disable it manually? Without changing anything else? I ask this because it seems "too easy" honestly and I have the feeling I missed a few steps.
Thank you in advance for your answers, I also apologize for the grammar and/or for any mistakes but English is not my mother language.
