According to the image in step 4 of here: http://www.ubuntu.com/download/desktop/install-ubuntu-desktop, I need to specify how much space I should allocate for Ubuntu. What does this mean? Is it referring to the space allocated for the OS itself, or programs included? I am planning to install Ubuntu on an SSD. I will also be installing my programs onto it. Then I have another HDD where my files will go. So how should I set up the dragger in that step to go with my situation? Also, this is an installation into a new build, so I have no previous OS installed, nor do I plan to dual-boost.
So based on what @heynnema told me and some other research I've done, this is what I understand I should do:
- Select the "Something else" installation type.
- Then I'll be taken to a screen similar to this: http://blog.sudobits.com/wp-content/uploads/2012/04/partition-manager.png but with just /dev/sda. And I understand that this is the SSD. So then I should click it and then "New Partition Table", thus providing "free space" for a total of about 120000 MB (120GB SSD).
- Then I should click "free space", and then click "Add". From there I should enter the max amount available, as shown in the previous screen next to "free space". And the "Type for the new partition" is "Logical", the "Location for the new partition" is "Beginning of this space", the option chosen for "Use as" is "Ext4 journaling file system", and the "Mount point" is "/". With those, I should click OK.
- Now I should be back to the screen I was when I first pressed "Something else" and continued. Then I'm not too sure at all, but I understand that I should change the dropdown for "Device for boot loader installation" to "/dev/sdb ...", which is the HDD. I'm not sure if I have to do this, or if I shouldn't touch that at all, leaving it at "/dev/sda ...", the SSD, and "/dev/sdb" should've been in the device list from the start. From there I should click "/dev/sdb" in the device list, again click "New Partition Table...", then the newly generated "free space", and "Add".
- In the screen that appears from pressing "Add", I should enter 20000 MB (16 GB, which is my total RAM, multiplied by 1.25, and of course converted to MB) for the "Size", "Primary" for the "Type for the new partition", "Beginning of this space" again for the "Location for the new partition", and "swap area" as the "Use as" dropdown option. Then I should click OK.
- Next I should again click free space under "/dev/sbd", and then "Add". Then I should enter the maximum size remaining on the HDD for the "Size" (which will be the amount shown in "free space" originally minus 20000 MB for the swap area). And then "Primary" for "Type for the new partition" (not positive if it should be Primary or Logical here), "Beginning of this space" for "Location for the new partition", "Ext4 journaling file system" for "Use as", and "/home" for "Mount point". Then Click OK, and "Install Now" on the following screen.
What I'm not too sure about is if the SSD will be sda and the HDD sdb. Is there a chance they'll be switched, and how will I know which one is which if so? Also, I've seen suggestions to add partitions for "/boot", "/tmp", and "/var". Is that something I should do, and how and where can I fit that into the steps above? And my understanding is that doing this makes it so the OS and all my programs/apps are installed on the SSD as to utilize the speed that is offered. And then all my documents, images, videos, files, etc. are on the HDD. Am I right in this?
