Samsung 970 evo not detected while installing

edit

I'm trying to install Fedora 29 Workstation in a NVMe M.2 Samsung 970 evo that already has another OS installed. I reserved about 30GiB (clean partition, it doesn't even have a file system assigned) for the "/" dir. I have another HD where I installed the OS, but I want to put it within the 970 evo.

When I was trying to configure the drive the M.2 wasn't listed. I checked with lspci and the dmesg and didn't even find anything related to the M.2.

Has anyone encountered something like this with a different HD/SSD?

I'm using: Dell Inspiron 15 7566. 1 TB HD Toshiba. 500 GB NVMe M.2 Samsung 970 evo.
