Hey all, i was hoping someone could shed some light on a problem i'm having while installing 12.10

Maybe i'm just not seeing the option somewhere, but it seems like if i choose to encrypt the whole disk during installation, i am unable to also manually partition my hdd...

If i choose the 'something else' option, i can manually partition the drive as i want to, but then the installation continues and doesn't seem to give me the whole disk encryption option, i only get the 'encrypt home directory' option later on.

So my question is, how do i choose the whole disk encryption option, while also being able to manually partition my drive?

Thanks
