install ubuntu on Dell XPS 15 (2 hard drives )

hi
i loved Ubuntu 14.04 so I'm switching as a primary system for my work ^_^

i have Dell XPS 15 Ultrabook (core i5 version)
this ultrabook comes with 2 hard drives , 32GB mSATA + 500GB and 8GB Ram , intel core i5, intel graphics

now my problem is in partitions how,
i have installed the ubuntu on the 32GB mSATA on / and 500GB for /home, and i created 8GB for swap on mSATA drive
and it's worked
but when i wanted to check the swap the system says there's no swap created,

please tell me what is the correct partition format should i do and after that please tell me how to encrypt the home folder and swap space

thanks very much

With 8GB, you are unlikely to use any swap space - unless it's for hibernation purposes.

I would investigate creating a swap file in /home - reserving a 25% of your mSata is a waste.
Use Google or similar to find out how to do it - it's just a few commands...
It's almost as fast as a separate partition.

If you want to encrypt /home, I think you would need to reinstall your system.
I would get used to using Ubuntu (or an alternate choice) first.

Thanks for the replay

I've set my bios boot option to UEFI
and now I'm on the Installation screen "Installation type" ( partitions screen )

I've created these partitions:
- Swap 4 GB on mSata (32GB drive)
- 250MB EFI partition on mSata (32GB drive )
- the rest of space about 25GB to / on (32GB mSATA Drive)

- 500GB (the second drive) to /home

note: someone told me to give the /usr about 10GB , i'm just confused a little bit

please let me know if this is the right settings or needs some modifications ?

please help me i'm still waiting

You may not want to creare seperate /usr ubuntu is testing systemd & might change to it in next release.
Systemd will complain about /usr being broken.
The changes might come as early as the 14.10 release or 15.04.
https://wiki.ubuntu.com/systemd
Also did you activate swap & add to /etc/fstab.
Not sure if you have to run

Your selections should work. There is not set or precise method and all of these are simply options/choices by the user. The base method is a / partition and a swap. As stated above, you will never use swap if you have 8GB of memory and having a separate /usr partition would also be a choice and I'm sure there are some situations where it might be useful. I've never done it but the link below explains some reasons for doing it.

Thanks for replay,
the system will be installed on 32GB mSATA HD
now the question is if i kept the /usr and the / on the same disk , will i have a problem in the future if i installed more software
because the software are usually installed under /usr or /opt

so my plan is mount /usr and /opt on a separate hdd
is that will be fine ?

I don't yet with just 8 gig for /.

Code:

df -h

Filesystem      Size  Used Avail Use% Mounted on

/dev/sda1      8.6G  5.0G  3.2G  62% /

none            4.0K    0  4.0K  0% /sys/fs/cgroup

udev            2.5G  4.0K  2.5G  1% /dev

tmpfs          501M  1.3M  500M  1% /run

none            5.0M    0  5.0M  0% /run/lock

none            2.5G  80K  2.5G  1% /run/shm

none            100M  20K  100M  1% /run/user

/dev/sda2      157G  23G  126G  16% /home

On this

Code:

$ inxi -M

Machine:  System: Dell product: Latitude XT2

          Mobo: Dell model: 0HJ48R Bios: Dell v: A01 date: 05/07/2009

I only have a 180 gig SSD in mine,

Code:

Drives:    HDD Total Size: 180.0GB (16.5% used)

          ID-1: /dev/sda model: D2CSTK181M11 size: 180.0GB

Partition: ID-1: / size: 8.6G used: 5.0G (62%) fs: ext4 dev: /dev/sda1 

          ID-2: /home size: 157G used: 23G (16%) fs: ext4 dev: /dev/sda2

If I had your Dell. I would during the install process. Point "/" to the 32 gig SSD. More than enough room for everything.
Then point "/home" to the 500 gig platter drive. Any /swap I would put on the 500 gig platter drive also.

Up to you though.

I will try to install the full os on / and separate /home on another hd
