I wanted to install selinux on Ubuntu 16.04. The system asked me to install grub-pc:



1



Since I don't know which option I should select, I looked for similar issues on the web and I noticed I don't have /dev/sda.



Could someone explain me what I am supposed to do and why I don't have /dev/sda?

    You have the newer NVMe SSD drive and your install is LVM with encryption. Grub-pc is for BIOS boot, almost all new NVMe drives are on newer UEFI systems using UEFI boot. But you are not showing an ESP - efi system partition, so maybe BIOS/CSM/Legacy install.
