I have a Dell XPS 8700 with an internal SSD (drive 0), an internal magnetic HD (drive 1) and two USB-connected HDs.
I booted from the DVD that Dell sent me ("Windows 8.1 Recovery Media for Windows 8.1 Products 64-bit"). Without asking which drive I wanted to install W8.1 on, it installed 8.0 on drive 1. It also divided drive 1 into 6 partitions, each with a letter.
1. Do I need for all of those partitions to have letters?
2. How do I get 8.1?
3. How do I install the OS on drive 0 the next time I do this?
