I'm purchasing a new computer (Dell Vostro desktop, 500GB HD) with a clean install of Win 7 Pro, and I plan on installing Mint so I can dual-boot. I've been researching the install process, both on-forum and off, and had some questions on different approaches.
One tutorial recommended adding four partitions to the existing Windows partitions: /boot, /, /home, and swap.
The other tutorial recommended adding two partitions: / and swap (and optionally, /home).
Both tutorials recommended retaining and using the Win bootloader and putting GRUB in the Mint partition.
I understand why the addition of a /home partition makes sense (or even a /data partition--I'm currently dual-booting XP and Ubuntu). But my question is: what is the rationale for adding a /boot AND a / partition vs. just a / partition?
