After nine months of not having booted my Windows even once, I think it’s time to wipe the Windows related partitions once and for all and claim the space. The problem is I think the way my partitions are structured, it may not be that easy. I am assuming everything other than the two ext4 partitions will have to go. What do you think? r/linux4noobs -
Someone even suggested I nuked the whole thing and started again, which would be the absolute last resort and only when I ran out of space.


The sda1 and sda2 partitions seem safe to format. Just be sure that you really copied everything you need from there. Like others said, better not to mess with the boot partitions
If you want to increase the space of the linux partitions, insead of creating a new extra partition, that may be a bit tricky in that layout, but one thing you can do is (from a live boot) is:
1- delete both windows partitions and create a new ext4 one with ~530gb
2 - clone your /home partition into there and change the fstab to point to the new partition
3- manually check if all your files were safely copied, just to be sure
4 - delete the old /home and expand the size of the / partition into it
you will end with a / partition with ~300gb and a /home of ~530gb
This looks fairly straightforward. I have done (1) already. It’s not great that
/will be that big, wasting around 200GB but the setup is definitely better than now and the risk is minimal.
