I recently got a t480 thinkpad with no OS on it. It used to be a company work laptop and was working before but now its got no OS on it and when I use an arch, ubuntu, or windows bootable install media to install a new OS on the SSD inside of this thing it shows the SSD as 0B and wont let me do anything with it. I have no idea. I tested a spare nvme ssd I had as well as the NVME SSD that the laptop came with and both of them dont work. I tried different install medias in different ports, tried different bios settings but cant figure this out.
PLEASE help
