UEFI installation on a 200+GB HDD partition

**Bill_L** · 27-Jun-2018, 13:13

I am Ready to commit install on my Toshiba S-70 Satellite laptop.
There will be a Windows 10 partition on the HDD.

Since it is UEFI, I need Leap 15 partition suggestions besides swap.
HDD partition Leap 15 will go on is 200GB +

Swap 6 to 8GB (physical memory is 4GB)
Boot 500MB or is it even needed?
/ 20 to 30GB. EXT4
/Home. ??GB EXT4 OR XFS ?
other(s) ??GB EXT4 OR ???

Hi
This is a dual boot UEFI setup with Tumbleweed/WinX same setup would be for Leap 15;

Code:

 lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 111.8G  0 disk 
├─sda1   8:1    0   260M  0 part /boot/efi {WinX and Tumbleweed}
├─sda2   8:2    0    16M  0 part {WinX}
├─sda3   8:3    0    40G  0 part / {Tumbleweed} btrfs
├─sda4   8:4    0    35G  0 part /data xfs
├─sda5   8:5    0     4G  0 part [SWAP] {Physical memory is 8GB}
├─sda6   8:6    0  31.8G  0 part {WinX}
└─sda7   8:7    0   789M  0 part {Created by WinX}

What is the current disk setup?

If you are using "ext4" for "/", then I would suggest the 30G. That gives some growth space such as might be needed if you want to install other applications. And it allows that software sizes will increase over the years when you own this computer.

No, you do not need a separate "/boot".

For swap size, that depends on how you plan using the computer.

What is the current disk setup?

Currently the disk has the all the things Win10 puts on it, and two Win10 partitions:
The 16MB system and another system about 800MB
Win10 RTM version and is 200GB
A Win10 Recovery partition approximately 700MB
Win10 Insider Preview version 264GB
Another Recovery partition approximately 500MB

I plan to keep the Insider Preview out of curiosity about Win10's future(still looking pretty bleak IMO).

I'm sorry I can't post a full list like your, but I am on my old desktop, and doing it from this afternoon's memory. But all of your WinX things above pretty much emulate mine except for sizes and I don't have /boot/efi(yet)

I am now thinking 40GB for "/"
The swap I indicated was a random decision because the HDD partition will have plenty of space for it. 4 to 6GB will probably suffice.

That's the size that I normally use. It should be fine.

Hi
So, I'm assuming there is space on the disk after the last partition in your output?

Ah, okay.

That first partition is your EFI partition. It is 100M.

The installer is going to want a bigger EFI partition. But that isn't really needed. So you will need to use the expert partitioner.

There are some screen images in my blog post about the partitioner. Go with Expert Partitioner, "start with existing partitions". That should display existing partitioning. Then click on that 100M partition (in left column). It is probably shown as "/dev/sda1". Then click the "Edit" toward the bottom of the screen. Set the partition to be mounted at "/boot/efi".

Next click on the partition itself (probably shows as "/dev/sda". There should be an ADD button. Click that to add a partition. I would suggest you add the root partition first, then swap, then "/home".

If you mess up, no harm is done. You can abort the install and nothing will have been actually changed on your disk. So it's okay to try a few times until you get it right.

When you are done, and click "Accept", the partitioner will complain that the EFI partition isn't at least 256M. Ignore that warning, and just continue.

No there isn't at this time.
I will remove one of the Windows 10 partitions (C: or E: {A decision I still have to make}) and it's corresponding recovery(GPT,WRE) partition to make room for a Leap 15 install.
