fdisk says 33,8 GB and not 80 GB

Normally grub install will not simply disable Windows[tm] booting but
include the Windows[tm] system into the grub menu.

Yes, edit the /etc/grub.conf. There are numerous postings here on the
list explaining which entries are needed to the grub.conf. Please use
the list archive search, i.e.

Of course as long as the filesystem is supported, the other Linux system
is visible for the second system. It will not automatically use the
other system's partitions and content.

Simply parallel install. You can share a /boot partition. Don't let the
installer format the existing partition. But be careful! I think you can
offer the 100MB for /boot easily and bypass possible accidents from
sharing /boot between multiple Linux installs.

Can you be more precise? The Anaconda installer and especially Disk
Druid made problems?

You know that you can only have 4 primary partitions and if you have
logical partitions then you can have max. 3 primary partitions, the 4th
will be used for the extended one.
