I am attempting to overwrite Windows and install Linux on a Lenovo S340 15 inch laptop. Ubuntu, Fedora, and Mint all boot off of USB when the BIOS has secure boot turned off. The mouse and ethernet work fine. However, the installer(s) do not see the disk. The running Linuxes do not see the disk. The BIOS does not appear to have any of the dialogs discussed in other Q/A posts. In particular, I see nothing associated with the disk (SSD). Has anyone else figured this out?
(I do not want to dual boot. I increasingly loath Windows 10 and have no need for it.)
