My problem: I have a 500Gb NVMe SSD with windows installed on it and an hardDrive in my laptop (it's a lenovo y720). Every time I look to install Ubuntu 18.04.02, it can only see my 1Tb hdd.
Here are all the things I already tried:
1- I shrink my C: (NVMe drive) to be sure there is 100Gb completely free for the installation.
2-I did the command chkdsk /f (windows shell)
3- I did the command powercfg –h off to make sure Windows does not interfere. (windows shell) https://ubuntuforums.org/showthread.php?t=2380454 (Leunam12)
4- I changed RAID SATA Controller to AHCI which my Windows did not appreciate at all. I then follow this forum wich states to update my sotrage drivers to Microsoft Storage Controller AND EVEN do that again but in safe Mode. https://samnicholls.net/2016/01/14/how-to-switch-sata-raid-to-ahci-windows-10-xps-13/
5- On the grub's booting options I pressed 'e' to changethe line beginning by linux. I add after quiet splash "nvme_core.default_ps_max_latency_us=200" (with and without the ""). This forum said that should make my Nvme visible in my installation: https://ubuntuforums.org/showthread.php?t=2408864&s=bc394f3491f72e1886eb667346864bd3&page=2
I think that is all. Ohh and here you can see what are always my choice in the installation:Ubuntu installation without Nvme optionenter image description here
