Is the Windows 10 OS loaded onto the SSD for faster boot up?

Any optical drives in this system? Are there any bays for any?

Per the specs- There are no optical drives, and the only included bays are internal.

Hello and thanks for your question!

This model does not come with an internal CD-ROM drive. You will have to purchase an external USB DVD or BluRay drive separately.
