Ubuntu 18.04 can't recognize my SSD
I got a new Lenovo Ideapad Flex 5, recently. Previously, I had been using a 10-year-old system. A lot of things have changed since then and I wasn't up-to-date with the latest tech.
So this new system has a single 500GB NVMe SSD and had Windows 10 pre-installed on it. Now I want to install Ubuntu as well (dual boot). For this, I shrunk my Windows partition to half (originally, there was only a single partition with Windows 10 installed on it).
Now I started the Ubuntu 18.04 setup (from a USB) and proceeded with installing it. But it couldn't recognize my SSD :(
So, I started digging in for a solution. I found that there's an option in the BIOS namely, SATA Controller Mode which was set to "Intel RST Premium" (the other option is AHCI).
A little bit lookup on the Internet tells me that Intel RST premium technology is an application for managing RAID arrays. So I am not sure what this BIOS option is.
I decided to just switch to AHCI mode but then I would have to re-install Windows 10 (which I don't want to). Furthermore, while changing to AHCI mode it gives me a warning - "Existing data stored on drivers will be erased when resetting controller mode. Proceed?", to which obviously I say No, because I don't know which "data" and "driver" is it talking about.
Also, let's say if I change to AHCI mode, do I lose some performance for Windows? (Oh c'mon, Intel RST Premium has cool words like rapid and premium in it. Don't tell me they are just for name's sake?!!)
Next, I also came across very similar questions on SE but some of them talk about how to switch to AHCI mode without re-installing Windows, while someone else talked about utilities such as dmraid
and mdadm
to configure things.
I am unsure what to do next. I just want to dual boot Windows and Ubuntu ...and live a peaceful life.

You can change RAID to AHCI without re-installing windows, see triplescomputers.com/blog/uncategorized/…

@BernardWei I had to do that exactly. But is there any other way to install Ubuntu without changing to AHCI (Intel RST offers some performance benefits, right?)

RAID does not offer any benefit over AHCI for single storage. Some NVMe drive offers AHCI interface but it severly slow down it's performance if used. If you know your drive is NVMe and support PCIe, you might want to by pass RAID or AHCI altogether. PCIe are 2 to 4 times faster than the fastest SATA speed.
