Excuse the top-posting but it makes sense in this case - UEFI involved.
First, I suggest getting a handle on what UEFI is about. Read, read, read. My
plan is to sketch it out before I do my next install - noting the relationship
between different partitions, boot loader location, etc. There is a good
discussion of UEFI and installation at
Now check out Ubuntu UEFI Documentation on how to install:
https://help.ubuntu.com/community/UEFI
and,

Here's another ref:

My brain can't wrap around that yet.
Some advise to shrink the Win partition using disk management tools in
Windows, noting that one may not be able to squeeze it too far because of some
unmovable info store on the disk.
Space: over the years, I've learned that Windows is a real hog for space. I
just reinstalled Win-7 because I was running out of space on a 50 GB
partition; I increased it to 75 GB! My partitioning for Xubuntu is:
/boot 3.3 GB, 4% used
/ 35 GB, 16%
/home 73 GB, 25%
Root is symbolized as "/" and is where most of the executable software lives.
I use a 128 GB SSD for the the OSes - Windows and Linux, with room to spare.
/home is on a second SSD. No swap partition is needed. If swap space is
needed, create a swap file but the need is rare if you have a goodly amount of
ram - probably not with 4 GB and almost certainly not with 8GB of ram. Linux
is very good at managing memory / ram.
Observations: it will pay in the long run to learn about UEFI. It is "the wave
of the future." Constrains claim that UEFI is a Microsoft plot of some sort.
Not so. While MS was involved, and naturally so, Intel and others were heavily
involved (see Wikipedia,
https://en.wikipedia.org/wiki/Unified_Extensible_Firmware_Interface).
Simply stated, UEFI goes beyond GRUB, and adds powerful and desirable
functionality that is not available in the bios, etc. We gotta learn about it
sooner or later. Sooner is better if UEFI is on your new computer.
My comments may not apply to distros other then Ubuntu and not to older
versions, e.g., pre-16.04.

What should I know to install 16.04 64 onto a Toshiba laptop with UEFI?
Or should I install newest non-LTS 17.10 version (but I read there were
some nasty issues with UEFI and 17.10).
Do I need to disable secure boot? Assume I do.
Shrunk C: for Linux space. The HD has 5 partitions. From “left to right”:
300MB Recovery
100MB EFI System
C: 500GB “where the exiting Win10 lives”
92GB Unallocated, gained from shrinking C:, aim to put / and swap
parts. there.
891MB Recovery
From what I read Grub has to “play nice” with EFI. My question is, when
I install, where do I install Grub? What do I do? I see an EFI partition
and don’t want to “hose” anything. There are lots of recopies and
concoctions when I google.
Thanks.
