Thanks Dave, I guess I was checking if the setup seems right.
r.e. the BIOS and Dell, when I did my first Dell Update which was for the BIOS, the laptop wouldn't boot anymore. Dell Support said I had to download something Dell sent me to a flash disk and when I booted, had to tweak a lot of settings to get it to boot again. Again, I've no idea what they did or if there is any files/partitions that were created.
Thanks again.
