After several attempts with fallbacks to the GParted LiveCD to really kill some partitons that the partition manager couldn't give up on I finally got the damn mess to install. Except of course md was complaining about not being able to bd_claim sda at every boot and mdadm kept reporting it had a bad superblock. I failed it, removed it, wiped it, copied it, fdisked it, added and re-added it, tried every solution suggested on the entire Internet and it still had errors. The odd thing is that the partition still seemed to sync.
