Installation alongside Windows 10 Home Edition

Sat Jan 5 18:01:21 UTC 2019

 Hi,

I am currently attempting to install Kubuntu 18.04.1 on a HP Pavilion
15-cr0001ng notebook which came preinstalled with Windows 10 Home Edition.
In preparation, I shrunk the C: drive to get some 400GB of free storage on
the (single) HDD. I then booted the Kubuntu 18.04.1 DVD (via an external
drive) downloaded from
http://cdimage.ubuntu.com/kubuntu/releases/18.04/release/kubuntu-18.04.1-desktop-amd64.iso

Unfortunately, the only options the installer offers are to use the entire
disk (which I definitively do not want) or to do some manual "juggling"
(which I'd like to avoid), see 01_installation_type.png
<https://drive.google.com/open?id=1RurYPo9djb1wHYhe2YoAUu0ZblwLPn9U>.

Both the "Installation type" and the "Prepare partitions" steps clearly
show the Windows installation and also the free space intended for the
Kubuntu installation (see also 02_prepare_partitions.png
<https://drive.google.com/open?id=1m0ZKXkwOuZSfbRXS8dw5cjg1oMhVDrY5>); yet,
there is no option to install Kubuntu alongside the Windows installation
(without having to resort to manual modification of partitions.

I also selected "Try Kubuntu" first, followed by an upgrade of packages via
WiFi (hoping that maybe also the installer would be updated to a newer
version). Without effect.

Is automatic installation alongside Windows really not supported? Did I
miss something?

See attachments for the output of parted and efibootmgr.

Two additional questions:

   1. Is it possible to either install solely to the spare partition
   (without *installing* grub but booting grub from the DVD and from there
   starting the HDD based Kubuntu) or to remove grub later on (if I should
   decide to revert to a Windows-only notebook)?
   2. The live DVD did not detect the built-in WiFi (I had to use one
   connected via USB instead) which is a RealTek RTL8821CE [10ec:c821] (see
   attached lspci.txt). Is this expected?

Thanks in advance for your support.

Kind regards
Ingolf
