I have SSD with installed both Windows 8.1 and Ubuntu 14.04. Windows has it's own UEFI starting partition and Linux has Legacy BIOS one. I would like to completely scratch Windows installation from this drive and give the whole space to Linux but I don't want to cause any damage to partition with /boot. My partitons:
/dev/sda[1-4] are basically Windows stuff which I want to delete. /dev/sda8 is my data directory, it can be deleted. /dev/sda5 is Linux /boot partition which should be untouched. /dev/sda6 is my root directory which I want to move back to the place in which currently sda1 lives on.
Is it safe to delete /dev/sda[1-4,8], move /dev/sda5 back and then move the whole /dev/sda6 back? What are any other proposals to avoid loosing my linux installation and boot partition? I'm not an experienced user.
