Install and partition advice

Postby jredwards » Mon Mar 20, 2017 1:45 pm

I'm going to install Mint as my first foray into Linux alongside Windows and I have a few questions following some reading around on the forum and elsewhere.

My system has a 512gb SSD and a 2TB HDD. As i understand from the user guide the recommended partitions for Linux are:

root: 20-30gb
swap: 1.5-2x RAM
home: whatever is left/want

Should I also consider a separate partition for /usr/local? If I understand correctly, this is where self installed applications will go that are not a core part of the OS. Is that correct? Where does apt-get/Synaptic install packages? So if I install the Anaconda python distribution, this would go in usr/local and I wont need to reinstall it if I decide to change or reinstall my OS?

As Windows is already installed, should i shrink the SSD and HDD before embarking on the Mint installation, or will the installer take care of this for me?

Is it possible to set the root, swap and usr/local partitions on the SSD and the home partition on the SSD?

I was thinking that as a simple starting point I would just divide both drives in 2. Is that a good place to start?

I will be using Linux mostly for coding (Windows too where MS interfaces are required).

thanks in advance for thoughts/advice.

Hello jredwards and Welcome to Linux Mint,

I would go with the following partitions:
/ 30gbs
swap 20% ram
/home rest of drive.
There is really no need to do /usr/local on a separate partition. I don't see any real advantage to that one.
apt and synaptic install programs where ever the programmer/ packager determine they should go.
mostly program executables are found in /usr/bin with menu entries in /usr/share/applications.
some promgrams are found in /usr/libs others install in /opt some may be in user/local.
here a good tutorial on the Linux file system structure you should spend some time familiarizing yourself with it.

Good luck and hope to see you around soon on linux mint :)

@ jredwards

First, please refer to this Tutorial about the peculiarities of UEFI/GPT systems ....... viewtopic.php?f=42&t=163126

-1. Yes, shrink the Win 10 partition/system.
0. Boot the Live LM 18.1 USB-stick or DVD in UEFI mode
1. With your dual-drive/disk configuration, you should choose the "Something else" install option for LM 18.1, with the Internet disconnected, and not "Install LM alongside Windows Boot Manager. ( viewtopic.php?t=241889 )
2. /sda is the SSD, where Win 10 has been pre-installed, and /sdb is the HDD.
3. create the / or root(system) partition on the free/unallocated disk space in the SSD or /sda - should be 30GB to 50GB in size.
4. create the /home and swap partitions on the free disk space of the HDD or /sdb - /home partition size as desired and swap partition = same as RAM size or bigger. Swap should not be on the SSD because it does a lot of writing and rewriting on the disk. The /home partition is usually for data storage of documents, photos, music and movies.
5. ensure that the "Device for boot loader installation" is the Windows EFI System Partition or Windows Boot Manager - usually it's /sda1 or /sda2, is about 200MB in size and formatted in FAT32.

You can also do the install with the HDD disconnected. In this case, you can choose "Install LM alongside Windows Boot Manager" = auto-partitioning of the SSD and auto-install of the Linux boot-loader. You can set the size of the Linux system by moving the slider on the partition table. By default, only / and swap partitions will be auto-created, ie no /home partition.
....... After the successful install and boot-up, you can reconnect the HDD and repartition your Linux system with the GParted program of the Live LM 18.1 media. But this requires some tech-savvyness.

Good luck.
