I'm trying to install Ubuntu Server 18.04 to dual boot with Windows. When I run the Ubuntu Server installer, it doesn't show any partitions on the disk and instead recognizes my entire disk as unformatted.
I've seen various questions about this and it seems to be related to errors on the partition table, thus fixed by gdisk. In my case, gdisk doesn't report any errors, and the report doesn't show overlapping partitions (as that also seems to be related).
After concluding it might not be a problem with my disk, I tried the Ubuntu Desktop installer, and it recognized all the partitions perfectly (in fact I installed it and am using it to try to fix this right now).
Is there anything the Ubuntu Server installer does differently from Ubuntu Desktop that I should be aware of (as far as I know they both use libparted), or am I missing something?
(I've seen something about zapping the GPT table, but I really don't see a reason to risk doing that if Ubuntu Desktop had no problems with it)
