Oddly enough, I was having a thunk (as opposed to thinking!) last night and thought that I should add info about how to partition while using the something else method, I just need to grab an old HDD and do a few screen shots which could then explain how people can partition while installing, the only drawback being is that the partitions might not be recognised and a reboot would be needed!.
When I built my latest PC a couple of months ago, I decided to make it so upgrading was as painless as possible. I have a 250GB SSD for the OS and Swap. I have an 2TB hard disk for /home and just for good measure I also have another 2TB hard disk for backup.
I partitioned the SSD with Gparted so there was a small partition for booting, mounted at /boot/efi, a 16GB Linux Swap partition at the end of the drive, with the rest as Ext4 mounted as /
I had Ubuntu-Mate 15.10 x64 on this and yesterday, after copying the 16.04 ISO to a USB stick, I booted into the installer and chose ‘Something Else’. I left /boot/efi and the Linux Swap partitions alone and clicked ‘Change’ for the partition that contained 15.10. I selected ‘format partition’ in there and mount to ‘/’.
I also clicked ‘Change’ on both 2TB hard disks and set them to mount as /home and /backup respectively.
I then proceed with the installation, which is very quick on the SSD drive.
Once finished, the PC is restarted and very quickly, I get to my login screen. I login then recreate the other users on my system (I created a list beforehand, ensuring they were created in the same order so that each gets the same User ID).
I then reinstall any software I had previously.
Because the personal settings for each user is stored in their home folders, the software just works. For example, Thunderbird is already configured because each user’s settings are already there. This goes for other software too.
I prefer to do a clean install as I have had problems with upgrading in the past.

Alternatively, consider a section using GParted to create partitions before beginning the installation process? I like this method as it’s far simpler to understand a drives layout, and partitions are ready to roll as installation begins.
Hope you didn’t “thunk” too hard, heard it can be quite taxing?!
You mean something like this Dave?:
How about a GParted overview (with a link to your full GParted guide) added as a possible first step on your installation guide? Something like… Before you begin installation, if partition changes are needed…
it was actually at the bottom of the guide and I moved it to the top!.
Beware of using the “Something else” method with UEFI systems. It took me three times before I had a booting Ubuntu MATE 16.04. I was switching from the BIOS world. The first two tries was specifying “/” as the entire SSD without swap, the third attempt was unplugging my HDD data drive (“just in case”) and using the “Erase disk” option – then deleting the swap afterwards.
I haven’t grasped what I was missing, but it needs a (U)EFI boot partition and some additional steps if using “Something else” method on a new, blank UEFI system. That’s a little something that the guides are missing.
I set up my SSD using Gparted prior to installation, creating /boot/efi, an EXT4 partition and Linux Swap. Then when I ran the installer (UEFI from a USB stick), I selected “Something else” and ensured the EXT4 partition was mounted as “/”. I already had "/home’ on another disk and just had to ensure it was mounted as that. I’ve done this a few times now and had no problems at all.
Thanks for sharing @Steve. I had another look at Ubiquity and just discovered there is an option to format a partition as “EFI System Partition”, so that explains why it didn’t boot the first two times and where to set one on a clean UEFI system in future.
I’m surprised Ubiquity didn’t ask me “Are you sure you don’t need a EFI partition?” like it does with swap.
thanks for the heads up, I have added this bit at the beginning of the guide as I personally don’t have any UEFI systems with which I can replicate the situation!:
People who have a PC/Notebook with UEFI, please see this link before commencing as it may be necessary to add a UEFI partition to your partition layout!!:
