I've recently bought a new Lenovo IdeaPad C340 with an M.2 SSD and Windows 10 preinstalled. Now I want to dual-boot it with Manjaro (Awesome WM edition, shouldn't matter through).
The problem: Neither the installer on the live USB, nor Gparted, nor even ls /dev
does detect the SSD.
After some research I discovered that my SSD is operating with Intel RST. In order to switch to AHCI, I followed this instruction. It worked fine, but the Laptop feeled so dramaticaly slower after that, even after several reboot, I didn't even need a benchmark to tell there's something wrong with the SSD. The start time went from under 5sec to ~30sec. Futhermore, I was unable to turn the laptop off / reboot it, as the power light just continues to glow (for a long time) even when the screen went dark. Further searching revealed that this is a common problem when switching to AHCI, and the only option is to reinstall Windows. Great.
Afterwards I switched back to Intel RST (using same instructions), and now try to get the Manjaro Live USB to detect the said SSD, with no luck so far. When I look at the RST options in the UEFI, the SSD is a non-RAID PCIe NVM SSD. (Of course, I only have one drive, why the hell is that thing set to RST in the first place?)
There are many tutorial / references / information out there describing how to make a RAID0 or RAID1 with RST, or how to accompish what I want by switching to AHCI. But I don't need this. I just want Manjaro to detect this SSD.
Is there any way to accomplish this by for example configuring it with mdadm
? Or is there any way one can fix that Windows issues without nuking and reinstalling it?
Note: USB-Boot is enabled, Secure Boot and Legacy Support disabled. Futhermore, /dev/mapping/control
is present, but no further devices are in /dev/mapping
and there are no /dev/dm-*
devices neither. And I'm not 100% sure if the problem is really with RST.
