I already regret making my root partition only 10Go. Between LaTeX and my dual 32/64-bits architecture (thanks videogames) I'm almost out of space.
@gracie Something like this:
/dev/sda1 ==> /boot/efi (199Mo)
/dev/sda2 ==> /boot (10Go)
/dev/sda3 ==> /opt (20Go)
/dev/sda4 ==> /home (930Go)
/dev/sda5 ==> swap (16Go)
nothing (24Go)
@Sylvhem your swap is enormous, you could happily give up most of that and grow your root partition; I'd drop that into the free space, carve out a new 20Go root partition, clone your existing root to that then drop it as well, make a smaller swap out of what's left and the rest free for windows or whatever (opt looks big, too, but shrinking a populated fs is a bit riskier)
