I have been facing this issue even when I boot through Gparted LiveCD. My goal is to install Windows dual booting with Ubuntu (My wife is not comfortable with linux)
Don't ask me about the ext2 and fat32 partitions here, I don't have any clue myself as to when and how they got created. Also let me know if it would be safe to remove these.
Suggestions? Advice?

is the ESP and you need it to boot in EFI+GPT.sda2
is certainly a boot partition and hold your kernel, and yes you need it.sudo update-grub
to get GRUB to recognize Windows.
